2.1 Authority and Purpose (formerly § 1.00)

1. A. These rules and regulations (Rules) are promulgated by the Coastal Resources Management Council (CRMC) pursuant to the requirements and provisions of the R.I. Gen. Laws § 46-23-6, as amended.
2. B. The CRMC shall be responsible for the protection and management of freshwater wetlands in the vicinity of the coast as depicted on maps maintained on file at the offices the CRMC and Rhode Island Department of Environmental Management (DEM), and the municipal offices of each coastal city or town. The CRMC may at any time, when necessary, consult with and/or coordinate its responsibilities and duties with the DEM.

3. C. These Rules are promulgated by the CRMC to:

   1. 1. Administer and enforce R.I. Gen. Laws § 46-23-6, as amended, in regard to freshwater wetlands in the vicinity of the coast; and
   2. 2. Preserve, protect, and restore the purity and integrity of all freshwater wetlands located in the vicinity of the coast within the State of Rhode Island so that these freshwater wetlands shall be available for all beneficial purposes, and thus protect the health, welfare, and general wellbeing of the people and the environment of Rhode Island.
4. D. These Rules supersede all previous Rules and Regulations Governing the Protection and Management of Freshwater Wetlands in the Vicinity of the Coast adopted by the CRMC pursuant to R.I. Gen. Laws § 46-23-6.

2.2 Administrative Findings (formerly § 2.00)

1. A. The declarations of intent and public policy enumerated by the General Assembly in R.I. Gen. Laws §§ 2-1-18 and 2-1-19 (Freshwater Wetlands Act) are hereby adopted as the administrative findings upon which these Rules are based.

2. B. Consistent with these declarations, the CRMC makes the following findings:

   1. 1. Freshwater wetlands are ecological systems performing functions that directly benefit the health, welfare and general wellbeing of people and the environment.
   2. 2. Any such freshwater wetland functions as an integrated ecological system, no portion or component of which is less worthy of regulatory protection than the wetland as a whole. Riverbank and areas of land within 50 feet (perimeter wetlands) are important integral components of the flowing body of water, or the swamp, marsh, bog, pond with which they are associated.

   3. 3. Freshwater wetlands perform specific functions and support specific values, including but not limited to the following:

      1. a. Wildlife and wildlife habitat: Freshwater wetlands are important areas for the production and maintenance of a diversity of wildlife. Wetlands provide habitat for individual species and communities of animals and plants. Animals include both game and non-game species, which may be either obligate or facultative, and which may be permanent residents, or seasonal or transient in nature. Wetlands serve as travel corridors; nesting, feeding, resting, nursery and brood-rearing sites; drinking water sources, and escape cover; and provide seasonal breeding, migration and over-wintering habitat for wildlife. Wetlands provide critical habitat for some plant and animal species, and provide habitat for rare animal and rare plant species.
      2. b. Recreation and aesthetics: Freshwater wetlands support active and passive recreational and aesthetic values that are important to the general public. Wetlands provide the opportunity for recreational activities, including but not limited to: hunting, fishing, trapping, cross-country skiing, ice skating, boating, water-skiing, canoeing, camping, swimming, bicycling, hiking, walking, horseback riding, harvesting of natural foods or plant materials, bird watching and other animal observation, education and nature studies, and photography. Aesthetic values include but are not limited to the visual, aural and cultural qualities of the wetland. Without limitation, these include the wetland’s prominence as a distinct feature in the local area, including its value as open space; whether it is a rare wetland type; whether it offers or provides suitable habitat for any rare animal or rare plant species; whether it has any outstanding or uncommon geomorphologic features; and whether it contains or may contain material of archaeological, historical, or cultural significance.
      3. c. Flood protection: Freshwater wetlands protect life and property from flooding and flood flows by storing, retaining, metering out and otherwise controlling flood waters from storm events. Wetlands also control the damaging impacts of flood flows by providing frictional resistance to flood flows, dissipating erosive forces, and helping to anchor the shoreline.
      4. d. Surface water and groundwater: Freshwater wetlands provide and maintain surface and groundwater supplies by acting as recharge or discharge areas, and, in the case of some ponds, acting as surface water reservoirs. Although groundwater recharge and discharge functions and values may vary seasonally, freshwater wetlands, either individually or cumulatively, may be an important factor in replenishing ground and surface water supplies, maintaining stream flows, transporting surface waters, and storing and distributing surface waters and groundwater during periods of drought.
      5. e. Water quality: Freshwater wetlands protect and maintain water quality by retaining and removing nutrients; filtering and removing pollutants; removing sediments; producing oxygen; reducing turbidity; maintaining or modifying stream flow; maintaining temperature and oxygen regimes in both standing and flowing surface waters; and providing and maintaining safe drinking water supplies.
   4. 4. The cumulative impact of incremental alterations to freshwater wetlands that occur at different times or in different locations within the same wetland system, or both, may constitute a significant alteration, even if a single proposed alteration may not in and of itself constitute a significant alteration.
   5. 5. Consistent with the purposes of the Act, it is the public policy of the State to preserve the purity and integrity of all freshwater wetlands in Rhode Island. Random, unnecessary or undesirable alteration of any freshwater wetland is contrary to the Act and not in the best public interest because of the adverse impacts of such alterations on wetland functions and values. The CRMC will deny any application for a project that will so alter any wetland.
   6. 6. The CRMC recognizes that dams have created freshwater wetlands that may provide important wildlife habitats and recreational areas and may provide other important functions, values and benefits such as flood storage areas. The CRMC recognizes that dams may also be historic resources (listed on the National Register of Historic Places or eligible for listing) and that preservation of such resources is desirable. Also, consistent with its responsibilities under R.I. Gen. Laws Chapter 46-19, Inspection of Dams and Reservoirs, the DEM has determined that many dams in the state are in disrepair and may present safety hazards to the public. The CRMC hereby acknowledges that, as a result of an analysis of alternatives for addressing a dam’s state of disrepair, the removal or substantial alteration of a dam may be required by the DEM for reasons of public safety. The CRMC finds that the removal or substantial alteration of a dam for public safety reasons may be deemed consistent with the authority and purposes of these Rules provided that no other feasible alternative is available and impacts related to the dam’s removal or alteration are assessed and acceptably mitigated in accordance with these Rules.

2.3 General Administration (formerly § 3.00)

1. A. Freshwater wetlands: The CRMC shall be responsible for administering and enforcing these Rules. These Rules shall be liberally construed to permit the CRMC to effectuate the purposes of R.I. Gen. Laws §§ 46-23-6, 2-1-18, and 2-1-19.

2. B. Freshwater wetlands in the vicinity of the coast: Pursuant to R.I. Gen. Laws § 46-23-6, as amended, freshwater wetlands in the vicinity of the coast are under the exclusive jurisdiction of the Rhode Island Coastal Resources Management Council (CRMC), including, after January 1, 2002, the renewal, transfer, modification and enforcement of permits originally issued by the Department of Environmental Management, with these exceptions:

   1. 1. The DEM shall retain jurisdiction over farming-related activities involving freshwater wetlands in the vicinity of the coast for insignificant alterations consistent with R.I. Gen. Laws §§ 2-1-22(i) and (j).
   2. 2. Any determination or permit, including any terms and conditions, issued by the DEM prior to August 18, 1999, shall remain valid for the time period specified in such determination or permit.
   3. 3. The DEM shall retain jurisdiction over any permits issued prior to January 1, 2002, that are the subject of an outstanding compliance order or other formal administrative, civil or criminal legal action initiated by the DEM for the purpose of litigating or settling that action.
   4. 4. The DEM shall retain sufficient jurisdiction over any permits or permit applications acted upon by the DEM prior to January 1, 2002, to permit the DEM to defend or settle any legal proceedings brought against it as a result of those actions.
   5. 5. Any compliance order issued or other civil or criminal enforcement action taken by the DEM prior to August 18, 1999, shall continue to be subject to the DEM authority and to be governed by the rules and regulations in effect at the time the order was issued or action taken.
   6. 6. Permits issued by the DEM for projects that lie on or that straddle the jurisdictional boundary shall be administered by the DEM in accordance with § 2.3(C) of this Part below.

3. C. Projects that lie on or cross the jurisdictional boundary

   1. 1. Applications for linear projects such as road or utility rights of way lying on the jurisdictional boundary established pursuant to R.I. Gen. Laws § 46-23-6 will be reviewed as follows:

      1. a. If the project is located entirely or partially either within a CRMC Special Area Management Plan or within 200 feet of a coastal shoreline feature, as defined by CRMC, then CRMC shall be the freshwater review agency.
      2. b. If the project is located entirely outside of any CRMC Special Area Management Plan and beyond 200 feet of a coastal shoreline feature, as defined by CRMC, then the DEM shall be the freshwater review agency.

   2. 2. Applications for projects that cross or fall on both sides of the jurisdictional boundary established pursuant to R.I. Gen. Laws § 46-23-6 will be reviewed as follows:

      1. a. If all of the freshwater wetlands are located seaward of the boundary, then CRMC shall be the freshwater wetland review agency.
      2. b. If all of the freshwater wetlands are located inland of the boundary, then the DEM shall be the freshwater wetland review agency.

      3. c. If the wetlands lie on both sides of the jurisdictional boundary and the project is non-linear in character, then:

         1. (1) Where the project is located entirely or partially either within a CRMC Special Area Management Plan or within 200 feet of a coastal shoreline feature, as defined by CRMC, then CRMC shall be the freshwater wetland review agency; or
         2. (2) Where the project is entirely outside of any Special Area Management Plan and is beyond 200 feet of a coastal shoreline feature, as defined by CRMC, then the DEM shall be the freshwater wetland review agency.
      4. d. For linear projects that are on both sides of the jurisdictional boundary, the DEM and CRMC shall jointly determine which agency will serve as the freshwater wetland review agency. This determination shall be made on a case-by-case basis in response to a written request from an applicant to CRMC, and be based on the following: the extent and location of the freshwater wetland or wetlands, the area and proximity of potential land disturbance, and the guidelines set forth in any applicable watershed plan. Within ten (10) business days of the receipt of a request for clarification from an applicant, the agency that retains jurisdiction shall so inform the applicant. Upon written notice to the applicant, the agency may extend the ten-(10) day deadline for up to an additional ten (10) business days for any reason. Although the goal of these provisions is to promote the designation of a single review agency, in the event that a project includes potential freshwater wetland alteration in both jurisdictional areas, the DEM and CRMC reserve the right to jointly exercise their jurisdiction.
   3. 3. The permitting agency for a project that is on the boundary or on both sides of the boundary shall renew, modify, transfer and enforce the permit according to the Rules (in the case of the DEM) or the rules and regulations (in the case of CRMC) that were in effect at the time the permit was issued.
   4. 4. The CRMC and DEM maintain at their respective offices maps illustrating the jurisdictional boundary between freshwater wetlands and freshwater wetlands in the vicinity of the coast.

2.5 Regulated Activities (formerly § 5.00)

1. A. Prohibitions (formerly § 5.01)

   1. 1. Except as provided in § 2.6 of this Part, a proposed project or activity which may alter any freshwater wetland may not be undertaken without a permit from the CRMC. Specifically, no person may excavate; drain; fill; place trash, garbage, sewage, road runoff, drainage ditch effluents, earth, rock, borrow, gravel, sand, clay, peat, or other materials or effluents upon; divert water flows into or out of; dike; dam; divert; clear; grade; construct in; add to or take from or otherwise change the character of any freshwater wetland as defined herein, in any way, without first obtaining a permit from the CRMC.

   2. 2. In addition to those projects or activities proposed either partially or wholly within freshwater wetlands, projects or activities taking place outside of freshwater wetlands which in all likelihood, because of their close proximity to wetlands, or because the size or nature of the project or activity will result in an alteration of the natural character of any freshwater wetland, may not be undertaken without a permit from the Department. Such projects generally include those which:

      1. a. Result in a change to the normal surface run-off characteristics which increases the rate or volume of water flowing into, or draining or diverting water away from, freshwater wetlands by such activities as:

         1. (1) Creating or significantly increasing impervious areas;
         2. (2) Modifying run-off characteristics by grading significant amounts of land area or clearing and permanently modifying significant amounts of vegetative cover on areas draining to freshwater wetlands;
         3. (3) Diversion of and concentration of surface run-off through swales, ditches, grading, drainage systems and other surface run-off conveyance systems to or away from freshwater wetlands; or

      2. b. Result in diversion of groundwater into or away from freshwater wetlands by:

         1. (1) Installation of subdrains which will lower groundwater elevations supplying freshwater wetlands or increase flow into wetlands;
         2. (2) Installation of underground utilities bedded in pervious materials which may act as a subdrain to divert groundwater away from, or concentrate such water to freshwater wetlands;
         3. (3) Installation of wells, other than wells intended for a single family home, which will remove significant amounts of water supplying or affecting any freshwater wetland; or
      3. c. Result in a modification to the quality of water reaching freshwater wetlands which could change their natural character; or
      4. d. Result in construction of a "new" onsite wastewater treatment system (OWTS) as defined by the DEM "Rules Establishing Minimum Standards Relating to Location, Design, Construction and Maintenance of Onsite Wastewater Treatment Systems" (250-RICR-150-10-6), where the leaching field of the OWTS is located within fifty feet (50') of any emergent, shrub or forested wetland; special aquatic site; area subject to flooding; or area subject to storm flowage.
   3. 3. No project or activity that may or will alter a freshwater wetland pursuant to §§ 2.5(A)(1) and (2) of this Part above may be undertaken unless it conforms at all times to all applicable permits and permit terms and conditions, and all representations made in all applicable permit applications.

2. B. Application types and decisions available (formerly § 5.02)

   1. 1. These Rules provide for the following types of application, with the CRMC’s actions and potential results as noted:

      1. a. Request to determine the presence of wetlands: The CRMC will inspect the applicant’s property to determine whether a regulated wetland is present on the property. If a regulated wetland is identified, the CRMC will identify the type(s) of such wetlands (see § 2.8(B) of this Part). The CRMC possesses the sole authority to determine which areas are deemed freshwater wetlands.
      2. b. Request to verify wetland edges: The CRMC will inspect wetland edge(s) delineated by the applicant and, if in substantial agreement with the documentation provided, will confirm the presence of identified wetlands and the location of their delineated edges (see § 2.8(C) of this Part). Furthermore, the CRMC will identify the type(s) of wetland(s) verified.

      3. c. Request for preliminary determination: The CRMC will review documents submitted by the applicant in support of the proposed project and will:

         1. (1) Issue a permit, with conditions, for an insignificant alteration of freshwater wetlands;
         2. (2) Issue a determination that a significant alteration has been proposed; or
         3. (3) Issue a determination that a permit is not required (see § 2.9(A) of this Part). A determination that a project represents a significant alteration is not a denial of a permit.
      4. d. Application to alter a freshwater wetland: This application must be submitted to obtain a permit for a proposed project that will, or is likely to, result in a significant alteration of a freshwater wetland. After thorough review of the application, including public comments received during the required 45-day notice period, the CRMC may either issue a permit to alter freshwater wetlands or deny the application (see § 2.10 of this Part).
      5. e. Application for emergency alteration: This application must be submitted either by the owner of the property or an appropriate official, orally or in writing, to request a permit for an emergency alteration in the event that public health or safety is at imminent risk (see § 2.11(A) of this Part).
      6. f. Application for permit renewal: This application must be submitted to renew a freshwater wetland permit that was granted as a result of a Request for Preliminary Determination or an Application to Alter a Freshwater Wetland (see § 2.11(B) of this Part).
      7. g. Application for permit modification: This application must be submitted to request approval of a minor modification to a previously permitted project (see § 2.11(C) of this Part).
      8. h. Application for permit transfer: This application may be submitted to request the transfer of a valid permit to a new property owner (see § 2.11(D) of this Part).
      9. i. Application relating to farmers: In general, this application must be submitted directly to the DEM’s Division of Agriculture and Resource Marketing for a determination as to whether the project represents an insignificant or a significant alteration in accordance with these Rules (see § 2.11(E) of this Part).

Any person may request a meeting with representatives of the CRMC to discuss regulatory procedures and requirements, to introduce a proposed project for an initial response and discussion, to discuss potential project design alternatives, and to discuss modifications to project designs. The following stipulations will apply:

      1. a. If the CRMC has determined the presence of wetlands on or adjacent to the subject property, verified the wetland edges on the property, or if the property is the subject of a previous or ongoing wetland permit application, a person may request a meeting directly with the CRMC. A meeting will be granted at the discretion of the CRMC based upon any statutory limitations.
      2. b. If there are no prior wetland determinations or decisions by the CRMC about the subject property, a person may request a Pre-application meeting with the CRMC.

   2. 2. Coordination with municipalities.

      1. a. Applicants are encouraged to review local zoning, planning and building ordinances that may be relevant to a proposed project as part of preparing a freshwater wetlands application for the CRMC.
      2. b. Coordination with appropriate municipal officials, as to aspects of a proposed project that may involve conflicts with requirements under these Rules, should be undertaken prior to the submission of an application to the CRMC for review and approval of a proposed project.
      3. c. The applicant may invite any appropriate municipal officials to pre-application meetings conducted at the CRMC, and the applicant is encouraged to do so for major land development projects.
   3. 3. Coordination with the DEM’s Onsite Wastewater Treatment System (OWTS) Program. The CRMC reserves the right to require that applications for the same proposed project be submitted concurrently to the DEM OWTS Program to enable the CRMC to undertake a joint review.

   4. 4. Processing of applications

      1. a. The CRMC will assign a number for identification purposes to each application, and shall notify the applicant of the receipt of the application and the number assigned to it. It is the responsibility of the applicant to refer to the assigned application number in all correspondence and inquiries regarding the subject application.
      2. b. The CRMC staff will process completed applications generally in the order in which properly completed initial application materials are received by the CRMC, except where potential competing demands of State and CRMC priorities dictate otherwise. The CRMC may process applications out of sequence when those applications are submitted with a certificate of critical economic concern in accordance with R.I. Gen. Laws Chapter 42-117. Requests for emergency alterations (§ 2.11(A) of this Part) will be processed immediately upon receipt.

   5. 5. Review for completeness.

      1. a. After the CRMC receives an application and assigns an application number, it will conduct a completeness review that will focus on administrative and technical reviews to determine whether the application’s essential elements, in proper form, have been received and are considered complete. If the CRMC finds that an application is not administratively or technically complete, the applicant will be so informed through a notice of deficiency from the CRMC.
      2. b. A request for a preliminary determination or an application to alter is complete when in the opinion of the CRMC it provides all of the requisite information necessary to process the application in accordance with R.I. Gen. Laws § 2-1-22(a) and these Rules. With respect to an Application to Alter, when the CRMC determines that the application is technically complete, it also will issue the required public notice (See § 2.10(C) of this Part).
   6. 6. Written response. All CRMC decisions, determinations or authorizations, with the exception of responses to Requests for Emergency Alterations, will be issued in writing only and signed by the CRMC.
   7. 7. Any determination, verification or permit received from the CRMC pursuant to any application involving freshwater wetlands does not obviate the need for the applicant to obtain any and all other necessary permits, and for the applicant and project to comply with all other applicable federal, state and local laws, regulations and ordinances.

8. H. Suspension of application process (formerly § 7.08)

   1. 1. In any of the following circumstances, the CRMC may at its discretion suspend the processing of an application, provided that it so advises the applicant in writing and where appropriate it conducts an investigation of the matter alleged in any of the following circumstances:

      1. a. Where the property with respect to which an application has been submitted is alleged to contain unauthorized alterations of freshwater wetlands, discovered either during the review of an application or during investigation of a complaint.
      2. b. Where the property with respect to which an application has been submitted is the subject of any unresolved violation of the Rules, or which is the subject of any non-compliance with a CRMC, administrative, or judicial consent agreement, order of the Council, or judgment, or where the property subject to unauthorized alterations is not restored to the satisfaction of the CRMC.
      3. c. Where information provided on the application form or in support of the application is misleading, false, erroneous or inconsistent with these Rules, incomplete or non-responsive to deficiencies identified by the CRMC.

9. I. Recording and transfer of permits (formerly § 7.09)

   1. 1. Pursuant to R.I. Gen. Laws § 2-1-22(f), whenever required by the terms and conditions of any permit or revised permit issued by the CRMC, the applicant shall record the permit or revised permit at his or her own expense in the land evidence records of the municipality or municipalities in which the property subject to the permit lies.
   2. 2. Any valid permit issued by the CRMC that has been recorded in the land evidence records of the municipality or municipalities in which the property subject to the permit is located is automatically transferred upon sale of the property to the new owner.
   3. 3. In the event a new property owner desires or needs a current permit reissued in his or her name, an application for permit transfer may be submitted to the CRMC in accordance with § 2.11(D) of this Part.
   4. 4. Pursuant to R.I. Gen. Laws § 2-1-22(f), the limit of disturbance, the conditions of approval and any other requirements set forth in any recorded permit shall apply to and be enforceable against all subsequent owners of the land subject to the permit, unless a new or modified permit has been obtained from the CRMC.

10. J. General fee requirements (formerly § 7.10)

    1. 1. The applicant must pay all required fees to the CRMC in full at the time the applicant submits any application or request for hearing.
    2. 2. The fees for proposed projects and activities are set forth in the fee schedule under § 2.7(K) of this Part.
    3. 3. The fees for certain proposed projects (e.g., reconstruction or new construction of roads, railways, or airport facilities and new utility installation, such as installation of major utility lines, pipes, etc.) shall be based on the estimated construction cost (“ECC”) of certain portions of such projects. The ECC must include the costs of construction activities such as materials, labor and equipment. The ECC shall not include the cost of land acquisition and consultant fees for planning, design and construction supervision. The ECC must be determined for all portions of the project that are proposed in or above any freshwater wetlands, and for those portions that are proposed in areas sloping/draining into on-site or adjacent freshwater wetlands.
    4. 4. The ECC for proposed projects must be documented and prepared by an appraiser, general contractor, engineer, land surveyor, architect, landscape architect or other appropriately qualified professional. Such documentation must be submitted by the applicant with the application. All ECCs shall be subject to review and acceptance by the CRMC. The CRMC may, when deemed necessary, require additional documentation and specific information regarding the ECC.

    5. 5. The CRMC will process an application only after receipt of the appropriate fee paid in full.

       1. a. Fees not based upon an ECC: If the CRMC determines that a fee not based upon an ECC is incorrect, the CRMC will inform the applicant what additional monies must be submitted.
       2. b. Fees based upon an ECC: If the CRMC determines that a fee based upon an ECC is substantially incorrect, the CRMC will so notify the applicant. The applicant must then either submit written documentation supporting its original calculation of the fee or submit additional monies to resolve any deficiency. When, in the opinion of the CRMC, the fee remains substantially incorrect, the CRMC will consider the application withdrawn, and will so notify the applicant.

    6. 6. Unless specified in the fee schedule, fees submitted to the CRMC are not refundable once the technical review of the application has commenced; however, for the original applicant only, the CRMC will apply fifty percent (50%) of the fee submitted for a request for preliminary determination to the cost of a new application for the project, if:

       1. a. A determination of significant alteration is issued and the original applicant subsequently files an application to alter freshwater wetlands for the proposed project within six (6) months of the date the preliminary determination was issued; or
       2. b. A determination of a significant alteration is issued with recommendations to prevent such an alteration, and the original applicant files a second request for preliminary determination that incorporates the recommendations, within six (6) months of the date of issue of the original preliminary determination.
    7. 7. All fees must be paid by check or money order made payable to the Rhode Island General Treasurer.
    8. 8. No application fees pursuant to these Rules are required for projects where the CRMC is the applicant

   2. 2. Site plans submitted for request to verify wetland edges must not depict any proposed project or activities.
   3. 3. The edge(s) of all freshwater wetlands should be identified by a qualified professional as specified in guidance documents available from the CRMC and shall be delineated in accordance with the specifications set forth in § 2.18 of this Part (Appendix 2).
   4. 4. Any delineation or identification of freshwater wetlands completed by a person other than the CRMC, including by an applicant or applicant’s agent, shall be valid only after review and written verification by the CRMC (See the procedures outlined in § 2.18 of this Part (Appendix 2)).

   5. 5. For verification purposes, the applicant must undertake the following steps:

      1. a. Identify each wetland edge that the applicant wishes to have verified on the property, and record the edge on a site plan.

         1. (1) The wetland edge on the property shall be flagged with sequentially numbered or lettered flags, and the flags must be placed at the wetland edge in sufficient numbers to clearly identify the edge to be verified. The distance between flags must allow for adequate visibility from one flag to another during the growing season.
         2. (2) The wetland edge shall be surveyed and recorded on the site plans showing the location and number/letter of the flag corresponding with those flags at the site.
         3. (3) In addition to the surveyed wetland edge, periodic measurements (i.e., at least one (1) for every one hundred feet (100') of surveyed edge) must be recorded on the site plan, indicating the distance from the surveyed edge to fixed reference points on the property. Fixed reference points on the property shall include, but are not limited to: stone walls, watercourses, roads, trails, buildings, structures, fences, cut transects or traverse lines, survey stakes with stations, or other features that allow confirmation of the location of the flagged wetland edge by field measurements.
      2. b. Identify the professional(s) conducting the delineation.
      3. c. Provide documentation on forms provided by the CRMC describing the reasoning used to delineate a particular wetland edge or any series of edges.

   6. 6. Contour elevations, while helpful on site plans, are not required for requests to verify wetland edges, except where

      1. a. a request to verify the edge of the 100-year flood plain has been made; or
      2. b. the wetland edge is located along or within a parcel exceeding ten (10) acres.
   7. 7. The CRMC will inspect the wetland edge(s) delineated by the applicant and, if in substantial agreement with the documentation provided by the applicant, confirm the presence of identified wetlands and the location of their delineated edges.
   8. 8. Any verification of a wetland edge or series of edges issued by the CRMC shall be valid for a period of three (3) years from the date of issue.
   9. 9. A request to verify wetlands edges file shall be considered closed if the applicant fails to answer any notification of application deficiency or any request for additional information from the CRMC within a period of six (6) months from the date of the deficiency letter or request.

4. D. Request for regulatory applicability (formerly § 8.04)

   1. 1. An applicant seeking a request for regulatory applicability should submit the following documents and adhere to the following requirements:

      1. a. A completed application form (§§ 2.7(A) and (B) of this Part);

      3. c. A plan drawn to scale, illustrating and describing current and proposed conditions based on measured distances, and including a clearly depicted limit of clearing and disturbance, a locus map, and the location of any wetlands or wetland edges of concern;
      4. d. A written project description including the purpose, size, and location of the project;
      5. e. A written description of how potential wetland impacts have been avoided to the maximum extent possible; and
      6. f. Photographs depicting the current site conditions in the area of the proposed work.
      7. g. While not required, a verified wetland edge may facilitate the applicability decision.
   2. 2. The CRMC will review information provided by the applicant, and determine whether the proposed project is exempt or otherwise will not alter the character of any wetland, or whether further application is required in accordance with these Rules. If the proposed project appears to involve an alteration to freshwater wetlands or if the application is not clear or is missing information, further application will be required.

2.9 Request for Preliminary Determination (formerly § 9.00)

1. A. Purpose and outcomes (formerly § 9.01)

   1. 1. A request for preliminary determination application may be submitted to the CRMC to receive a determination as to whether or not a proposed project represents a significant alteration.

         1. (1) Avoidance: All persons must satisfactorily demonstrate to the CRMC in the form of a written narrative that all probable impacts to freshwater wetlands functions and values have been avoided to the maximum extent possible. The written narrative must describe what steps were taken to avoid impacts to freshwater wetlands. At a minimum, applicants must consider and address the following issues:

            1. (AA) Whether the primary proposed activity is water-dependent or whether it requires access to freshwater wetlands as a central element of its primary purpose (e.g., a pier);
            2. (BB) Whether any areas within the same property or other properties owned or controlled by the applicant could be used to achieve the project purpose without altering the natural character of any freshwater wetlands;
            3. (CC) Whether any other properties reasonably available to, but not currently owned or controlled by, the applicant could be used to achieve the project purpose while avoiding wetland alterations. A property is reasonably available if, in whole or in part, it can be acquired without excessive cost, taking individual circumstances into account, or, in the case of property owned or controlled by the same family, entity, group of affiliated entities, or local, state or federal government, may be obtained without excessive hardship;
            4. (DD) Whether alternative designs, layouts or technologies could be used to avoid freshwater wetlands or impacts on functions and values on the subject property or whether the project purpose could be achieved on other property that is reasonably available and would avoid wetlands;
            5. (EE) Whether the applicant has made any attempts (and if so what they were) to avoid alterations to freshwater wetlands by overcoming or removing constraints imposed by zoning, infrastructure, parcel size or the like; and
            6. (FF) Whether the feasible alternatives that would not alter the natural character of any freshwater wetlands on the subject property or on property that is reasonably available, if incorporated into the proposed project would adversely affect public health, safety or the environment.

         2. (2) Minimization: For any impact to freshwater wetlands that cannot be avoided, the applicant must satisfactorily demonstrate to the CRMC in the written narrative that the impact to wetland functions and values have been reduced to the maximum extent possible. At a minimum, applicants must consider and address the following issues:

            1. (AA) Whether the proposed project is necessary at the proposed scale or whether the scale of the wetland alteration could be reduced and still achieve the project purpose;
            2. (BB) Whether the proposed project is necessary at the proposed location or whether another location within the site could achieve the project purpose while resulting in less impact to the wetland;
            3. (CC) Whether there are feasible alternative designs, layouts, densities or technologies, that would result in less impact to the wetland while still achieving the project purpose; and
            4. (DD) Whether reduction in the scale or relocation of the proposed project to minimize impact to the wetland would result in adverse consequences to public health, safety or the environment.

         3. (3) Mitigation measures. Measures, methods, or best management practices to avoid alterations of and minimize impacts to wetlands include, but are not limited to:

            1. (AA) Preserving natural areas in and around wetlands;
            2. (BB)) Minimizing the extent of disturbed areas and encouraging the preservation of land in its natural state;

               1. (i) to "buffer" impacts from loss of wildlife habitat and loss of natural areas and
               2. (ii) to reduce the impacts of noise, lighting and other disturbances upon wildlife and the remaining natural areas;
            4. (DD) Maintaining unrestricted fish and wildlife passage;
            5. (EE) Designing structures and alterations so that they are located outside of flood plain, floodway, areas subject to flooding, flowing bodies of water or other freshwater wetlands;
            6. (FF) Using best management practices for the stabilization of disturbed areas and the selection, use, and maintenance of temporary or permanent soil erosion and sediment controls in accordance with the latest version of the RI Soil Erosion and Sediment Control Handbook and the RI DEM “Stormwater Management, Design and Installation Rules”, 250-RICR-150-10-8;
            7. (GG) Using best management practice selection and design criteria in accordance with the latest version of the RI DEM “Stormwater Management, Design and Installation Rules,” 250-RICR-150-10-8, to reduce post-development stormwater flows and maximize the control, treatment and maintenance of systems that reduce stormwater impacts to acceptable levels;
            8. (HH) Minimizing impervious surface areas such as roads, parking, paving or other surfaces;
            9. (II) Incorporating compensatory flood storage area(s) where necessary and in compliance with these Rules;
            10. (JJ) Encouraging infiltration of non-contaminated run-off into uncontaminated soils;

2.17 Appendix 1: Insignificant Alterations

1. A. In accordance with § 2.9(C) of this Part, the CRMC may issue a permit for proposed projects submitted under a request for preliminary determination application provided the proposed project represents, in the opinion of the CRMC, an insignificant alteration. The purpose of this section of the Appendix is to allow applicants and the public to determine with some likelihood what, under normal circumstances, represents an insignificant alteration.
2. B. The following represent examples of insignificant alterations. However, the applicant should be aware that certain circumstances peculiar to specific wetlands, the surrounding area, site conditions, and the proposed project, may result in a determination by the CRMC that a particular proposal represents a significant alteration and therefore requires filing of an application to alter and a permit from the CRMC. Therefore, even if a proposed project appears to fit within the examples of insignificant alterations in this Appendix, a permit by the CRMC is not implied or guaranteed. In addition, the proponent of a proposed project that fits or appears to fit within the examples of insignificant alterations still must seek a permit from the CRMC through a request for preliminary determination application before proceeding with the proposed project. Further, the proposed project must not result in the disturbance or destruction of any rare species or rare wetland type.

3. C. Examples of insignificant alterations include the following:

   1. 1. Construction and installation of a single new dock or single detached floats (excluding those regulated under § 1.3.1(D) of this Subchapter) only where:

      1. a. The dock is supported by floats or piles, extends perpendicular to the shoreline out to, but not exceeding, twenty feet (20'), and does not exceed six feet (6') in width;
      2. b. The float does not exceed one hundred and twenty (120) square feet in area;
      3. c. The installation and placement of the dock or float poses no hazard to boating safety or navigation in any body of water including any pond, river, or stream;
      4. d. The dock or float is placed no closer than twenty feet (20') to any neighboring property line on land or superficially extending over the waterbody;
      5. e. Any new access paths to the dock do not exceed five feet (5') in width, and do not result in fill, road construction, or any other clearing of the wetland, area(s) of land within fifty (50) feet, riverbank, and flood plains for access;
      6. f. The dock does not extend into or obstruct a floodway; and
      7. g. Pilings and/or posts permit reasonably unobstructed flow of water.

   2. 2. Minor revisions to residential or small lot commercial or industrial projects already approved by the CRMC only where:

      1. a. The revised alterations do not expand the area of disturbance any further into wetland, area(s) of land within fifty (50) feet, riverbank, and flood plains so as to negatively affect functions and values; and
      2. b. Compensation for loss in flood storage volume is maintained as approved.
      3. c. Such projects may include the revised location or configuration of structures, the minor relocation of onsite wastewater treatment systems (consistent with § 2.11(B) of this Part), walls, utility lines, or grade changes.

   3. 3. Construction and development activities that are not exempt pursuant to §§ 2.6(E) and (F) of this Part and are within wetland areas already developed for human activity only where:

      1. a. The area for proposed construction is now occupied by approved or existing buildings, parking or paved area, equipment storage, or materials storage;
      2. b. The construction and development does not propose to expand into wetlands which would result in negative effects on wetland functions and values; and
      3. c. The applicant complies with all requirements in these Rules associated with changes in runoff, water quality, and flood storage.
      4. d. In such projects where a more intensive use of the property is proposed which would result in increases in the level or duration of noise, lighting or other activities which could impact wildlife in adjacent natural wetlands a well-designed buffer zone must be incorporated into the proposed project design and placed between the project and any remaining undeveloped wetland.

   4. 4. Minor excavated pond construction (less than one-quarter (1/4) acre for new ponds and re-excavation for existing ponds) only where:

      1. a. The pond is located mostly adjacent to, or only partially in, any swamp, marsh, or other emergent, shrub or forested wetland;
      2. b. All spoils from excavation are removed to an upland location away from all wetlands;
      3. c. The construction or re-excavation does not result in the diversion, damming, or diking of any type of watercourse other than surface seepage from groundwater discharges;
      4. d. Re-excavation of an area less than 2,500 square feet of existing pond is accomplished for maintenance purposes to remove accumulated inorganic sediments or concentrated areas of problem emergents or aquatic weeds such as tall reed (Phragmites australis) or purple loosestrife (Lythrum salicaria). The excavation must be limited to concentrated problem areas and must incorporate all proper controls to protect the adjacent wetland environment; and
      5. e. The activity does not result in the loss of the only natural vegetated area adjacent to a swamp, marsh, or other emergent, shrub or forested wetland.
      6. f. Such projects must either incorporate the use of a well-designed buffer zone to minimize impacts to wildlife, or be sufficiently away from human activity so as to minimize interaction between humans and wildlife.

   5. 5. New construction and development of residential homes, commercial or industrial buildings and subdivisions incorporating such construction only where:

      1. a. The construction and all associated activity is proposed outside of all wetlands (including perimeter and riverbank wetlands);
      2. b. The project is designed to meet or exceed, and the applicant's registered professional engineer certifies that the project will meet or exceed, all best management practices to prevent the alteration of freshwater wetland functions and values due to changes in run-off/stormwater flows, water quality, flood storage, and erosion and sedimentation. Best management practices in this case must, at a minimum, address the requirements and recommendations specified in the latest edition of the Rhode Island “Stormwater Management, Design and Installation Rules,” 250-RICR-150-10-8, and the Rhode Island Soil Erosion and Sediment Control Handbook.
      3. c. The project design ensures the protection of all wetland functions and values (e.g., the design does not propose a building or structure at the edge of wetlands without considering the extent of clearing, grading and soil disturbance which may be necessary for equipment access, safety and other normal construction activity and human use needs).

   6. 6. Utility line or pipe installation where:

      1. a. The installation of the line or pipe is taking place within an existing maintained (cut/cleared) utility easement which already contains utility lines or pipes;
      2. b. Wetlands existing in the maintained (cut/cleared) existing utility easement are only temporarily altered to install the line or pipe;
      3. c. Culverts and the flow of water under bridges in roads or highways are not permanently blocked or disrupted by going under or attaching to such structure;
      4. d. The project does not cause any diversion of ground or surface water to or from any wetlands;
      5. e. The preconstruction contours are restored immediately upon installation;
      6. f. All work in any wetlands in the easement is undertaken during low flow periods;
      7. g. All disturbed areas are revegetated after restoring contours; and
      8. h. The project design incorporates best management practices for dewatering excavated areas.

   7. 7. Replacement of existing or approved bridges and culverts other than those exempt pursuant to § 2.6(C)(1)(b) of this Part only where:

      1. a. The replacement structure is similar to the existing structure in terms of physical size, invert elevations and flow capacity;
      2. b. Soil disturbance and construction activity in flowing water are reduced to the maximum extent possible; and
      3. c. The replacement structure accommodates and provides for wildlife passage where applicable.

   8. 8. Driveway and access road construction over watercourses such as drainage ditches, and areas subject to storm flowage only where:

      1. a. The watercourse and its adjacent banks are located within heavily developed residential, commercial or industrial areas;
      2. b. The driveway or access road is designed only to widths necessary to safely pass vehicles;
      3. c. The watercourse is not within another type of wetland such as a swamp, marsh, bog, pond or other emergent, shrub, or forested wetland, special aquatic site, perimeter wetland, or riverbank;
      4. d. All culverts are designed to meet the protection requirements of wetland, area(s) of land within fifty (50) feet, riverbank, and flood plain functions and values as specified in these Rules; and

       4. d. Following installation, the wetland area is revegetated.

2.18 Appendix 2: Specific Criteria for Identifying Wetland Edges

1. A. Vegetated wetlands

   1. 1. The landward edge of vegetated wetlands (i.e., bogs; marshes; swamps; emergent, shrub or forested wetlands; or similar types, including wetland complexes of these types), shall, under normal conditions, be identified as the place where the plant community associated with the vegetated wetland is no longer dominated by hydrophytes/hydrophytic vegetation (i.e., the plant community is composed of less than or equal to fifty percent (50%) hydrophytes/hydrophytic vegetation).

   2. 2. Hydrophytes/hydrophytic vegetation includes, but is not limited to:

      1. a. Those typical plant species listed in R.I. Gen. Laws §§ 2-1-20(3) "bog", (10) "marsh" and (16) "swamp"; or
      2. b. Those plant species listed as having a wetland indicator status of obligate (OBL) according to the most recent edition of the National List of Plant Species That Occur in Wetlands: Rhode Island (National List), as prepared by the U.S. Fish and Wildlife Service; or
      3. c. Those plant species listed as having a wetland indicator status of facultative wetland (FACW), facultative (FAC) or facultative upland (FACU) according to the National List, where such plants are present along with other clear hydrologic indicators of wetland.
   3. 3. Where no distinct edge is apparent based upon examination of vegetation alone (e.g., the plant community is transitional in nature and dominated by species having an indicator status of FACW, FAC or FACU), other hydrologic indicators must be considered before determining the location of the landward edge of vegetated wetlands. Where such indicators are present, the FACW, FAC, or FACU plant species are considered hydrophytes/hydrophytic vegetation; however, the landward edge of vegetated wetland in such transitional areas is located where other hydrologic indicators are no longer present.

   4. 4. Other hydrologic indicators are those characteristics, other than vegetation, which provide evidence that an area is continuously or periodically saturated, inundated, flooded, or ponded; has standing or slowly moving water; or frequently collects surface run-off or drainage. Examples of other hydrologic indicators include, but are not limited to, the following: (Note: Those features followed by an asterisk (*) are valid indicators only when at least one additional hydrologic indicator is present.)

      1. a. Morphologic features or properties associated with hydric soils in accordance with the most recent version of the Field Indicators for Identifying Hydric Soils in New England.
      2. b. Visual observation of soil saturation within twelve inches (12”) of the soil surface (considering both seasonal and recent weather conditions);
      3. c. Distinct water marks on vegetation or other fixed objects;*
      4. d. Sulfitic materials (H2S – rotten egg odor) within twelve inches (12”) of the soil surface;
      5. e. Mound and pool microtopography;*
      6. f. Patches of peat mosses (Sphagnum spp.)
      7. g. Soil morphologic evidence of recent or periodic flooding (e.g., stratification associated with flood plains);*
      8. h. Visual observation of surface inundation (considering both seasonal and recent weather conditions);*
      9. i. Dark or water-stained leaves on the ground surface;*
      10. j. Drift or wrack lines of water-borne materials; *
      11. k. Wetland drainage features or patterns such as scoured channels;*
      12. l. Morphological plant adaptations (e.g., buttressed trees trunks, adventitious roots, exposed or shallow root systems);*
      13. m. Distinct or prominent pore linings (oxidized rhizopheres) along live roots within twelve inches (12”) of the soil surface.*

   5. 5. For purposes of locating and identifying the edge of vegetated wetlands for applications submitted to the CRMC, the CRMC will accept the methodology described and incorporated within the Corps of Engineers Wetlands Delineation Manual, Technical Report Y - 87-1, January, 1987, Prepared for: Department of The Army, U.S. Army Corps of Engineers, (Corps) in addition to the Corps’ September 9, 1991 regulatory guidance letter regarding Guidance for the Interpretation of Wetland Boundaries Using the 1987 Corps Manual in the Six New England States under the following conditions:

      1. a. The use of this methodology is intended to facilitate the location and identification of the edge of "vegetated" wetlands, but must not be interpreted as redefining wetlands regulated under the Act and these Rules. For example, the area of land within fifty feet (50') of any bog; marsh; swamp; or pond is a regulated wetland according to R.I. Gen. Laws § 2-1-20(4); however, the Manual, for purposes of Section 404 of the Clean Water Act, will refer to these areas as "nonwetlands."
      2. b. All edge locations and delineations are subject to the CRMC’s review and acceptance under the procedures set forth in § 2.8(B) of this Part for requests to determine the presence of wetlands. Accordingly, all requests to verify the edge of these types of wetlands will require on-site inspection and analysis.
      3. c. Areas discovered during the delineation of freshwater wetlands which appear to have altered conditions (e.g., removal of vegetation, ditching, draining, filling or other alterations that have changed or appear to change normal conditions) must be documented.
2. B. Perimeter wetlands. The edge of perimeter wetlands shall be identified as the line fifty feet (50’) from the landward edge of any bog, marsh, swamp, or pond.

3. C. Flowing and standing water wetlands

   1. 1. The edge of rivers, streams, intermittent streams, ponds, special aquatic sites, areas subject to storm flowage, areas subject to flooding and other areas dominated by open or flowing water shall be identified as follows:

      1. a. The edge of rivers, streams, intermittent streams, ponds, special aquatic sites, areas subject to storm flowage, areas subject to flooding and other areas dominated by open or flowing water shall be the ordinary high water mark of standing or flowing water. The ordinary high water mark is the line separating land flooded at high water and land exposed at high water. This line may be determined and documented by using recorded hydrologic data (e.g., data obtained from site specific planning and design documents; in-stream flow studies; stream gauge data; the CRMC’s file data; or flood data), or, in the absence of these, by observing physical characteristics, such as evidence of a clear demarcation line between terrestrial and aquatic conditions as a result of standing or flowing water; shelving; permanent watermarks and stains on woody vegetation or other fixed objects, such as bridges, stones, walls, docks, or piers; changes in the character of the soil; the presence of water-borne natural litter and debris; evidence of surface scouring; or other appropriate means.
      2. b. The edge of any pond and incoming or outgoing flowing body of water shall be that location where characteristics associated with a lentic ecosystem and a lotic ecosystem are both present.

4. D. Riverbank wetlands. The edge of riverbank wetlands along a river, stream, intermittent stream, or flowing body of water shall be determined by the method described herein:

   1. 1. The CRMC may compile designated riverbank widths for flowing water body segments and maintain this information on file. Such designations shall be based upon currently available maps, aerial photographs, observations, and past determinations by the CRMC. All applicants may consult with the CRMC regarding the availability of designated riverbank widths along any flowing bodies of water segments in the project area. If a riverbank width has been determined by the CRMC, this designation can be used to preclude the need for the applicant to undertake field measurements or observations.

   2. 2. When designated riverbank widths are not available, the identification and assignment of a riverbank width shall, if the width is not obvious, be conducted using the following method:

      1. a. The width of the flowing body of water shall be measured along the channel’s length at a minimum of five (5) locations upstream and at a minimum of five (5) locations downstream from a measured midpoint within the project area or area of concern.

         1. (1) The measurements shall be taken at the midpoint, and at approximately equal intervals along the channel’s length with the minimum distance between intervals not less than twenty feet (20’) and the maximum distance between intervals not exceeding fifty feet (50’).
         2. (2) The midpoint of the measurements shall be near the midpoint of the project area or area of concern.
         3. (3) The measurements shall be taken between the edges of the flowing body of water or channel as delineated according to § 2.18(C)(1)(a) of this Part above.
         4. (4) All measurements shall be taken at locations that are representative of the water body segment, must be documented as to the locations, and must be able to be reproduced. Measurements taken at any human-induced restrictions which are less than the natural conditions or within sections of the flowing body of water subject to unauthorized alterations are not applicable or acceptable.

      2. b. The arithmetic average or mean of the channel width measurements shall serve as the average channel width for the purposes of assigning riverbank. The mean shall be calculated using the formula:

         X1 + X2 + ... + Xn

         n

         where “X” equals each channel width measurement and “n” equals the number of measurements.

      3. c. When the mean channel width is less than ten feet (10’), the riverbank wetland shall be one hundred feet (100’). When the mean channel width is ten feet (10’) or more, the riverbank wetland shall be two hundred feet (200’).

5. E. Flood plain wetlands. The edge of any flood plain shall be identified as the maximum horizontal extent of flood water which will result from the statistical 100-year frequency storm event.

   1. 1. The 100-year flood plain elevation shall be determined by the most recently available flood profile data prepared under the National Flood Insurance Program of the Federal Emergency Management Agency (FEMA); or

   2. 2. In the event that FEMA flood profile data are unavailable, or if the applicant disagrees with the data, the flood plain edge shall be determined by engineering calculations completed by a registered professional engineer. These calculations shall be:

      1. a. Based upon a widely accepted hydrologic and hydraulic model (e.g., HEC-RAS). The applicant must demonstrate that the selected model is appropriate for the determination; and
      2. b. Based upon a design storm of at least seven inches (7”) of precipitation in twenty-four (24) hours (a Type III rainfall as defined by the National Weather Service).
   3. 3. The flood plain edge must coincide with the flood plain elevation and topographic contour elevations as depicted on submitted plans. Transposing flood boundaries from FEMA maps by using horizontal scaling is not acceptable for plans submitted to the CRMC. Identification of the 100-year flood elevation must be expressed in North American Vertical Datum (NAVD 1988) as related to Mean Sea Level.
