   6. 6. an STGU on an Eligible Landfill located on the same parcel as another STGU on an Eligible Landfill, provided that the STGU is separately metered from the original STGU and that the total capacity qualified for the parcel is less than or equal to 10,000 kW;
   7. 7. an STGU 25 kW or less or a Building Mounted STGU, which is located on the same building as another STGU, provided that the STGU is separately metered from the original STGU and is connected to a meter of a separate End-use Customer as the original STGU;
   8. 8. an STGU located on the same parcel that submits a Statement of Qualification Application at least twelve months after the Commercial Operation Date of the original STGU and is separately metered or that can demonstrate to the Department's satisfaction that the Owners of the STGUs are unaffiliated parties;
   9. 9. an STGU that is physically located on a parcel or parcels of land owned or controlled by the Massachusetts Department of Transportation as established by M.G.L. c. 6C and can demonstrate to the Department's satisfaction that it should be granted an exception to the provisions of 225 CMR 28.08(5); and
   10. 10. an STGU that can demonstrate to the Department's satisfaction that it should be granted an exception to the provisions of 225 CMR 28.08(5) for good cause.

(6) Environmental Monitor. All STGUs qualifying as Dual-use Agricultural STGUs or subject to the requirements of 225 CMR 28.09 shall work with the Environmental Monitor pursuant to the following requirements.

1. (a) Payment of Fees. Applicants shall be responsible for the payment of fees for the cost of the Environmental Monitor's site visits, compliance certification, and other related activities.

2. (b) Site Visits. The Environmental Monitor shall conduct site visits to the location of the STGU to ensure compliance with the Performance Standards detailed in 225 CMR 28.08(7) and provide recommendations on minimizing site impacts.

   1. 1. A minimum of two site visits shall occur, one prior to the Department issuing a Preliminary Statement of Qualification and one prior to the Department issuing a Final Statement of Qualification. STGUs that submit a Statement of Qualification Application in the initial ten-day application window under 225 CMR 28.06(4)(b) for Program Year 2025 or Program Year 2026 may be issued a Preliminary Statement of Qualification prior to an initial visit from the Environmental Monitor. Such STGUs shall have a site visit from the Environmental Monitor within 90 days of receiving their Preliminary Statement of Qualification. Subject to the availability of the Environmental Monitor, the Department may extend the 90-day window on a case-by-case basis.
   2. 2. The Department may require additional site visits by the Environmental Monitor as necessary.
   3. 3. Site visits may occur during all stages of project development and up to two years following Mechanical Completion.
   4. 4. Applicants shall ensure that the Environmental Monitor has adequate access to project facilities and information required to ensure compliance with the Performance Standards.

(7) Performance Standards. All STGUs qualifying as Dual-use Agricultural STGUs or subject to the requirements of 225 CMR 28.09 shall work with the Environmental Monitor to obtain a certification that the construction of the STGU complies with the below standards. In the event that compliance with one or more listed Performance Standards conflicts with a permit requirement imposed by an authority having jurisdiction, compliance with the permit requirement shall take precedence and the Environmental Monitor shall deem the STGU in compliance with the applicable Performance Standard.

1. (a) no removal of field soils;
2. (b) existing leveled field areas shall be left as is without disturbance;
3. (c) where soils need to be leveled and smoothed, such as filling potholes or leveling, this shall be done with minimal overall impact with all displaced soils returned to the areas affected;
4. (d) ballasts, screw-type, or post driven pilings and other acceptable minimal soil impact methods that do not require footings or other permanent penetration of soils for mounting are required, unless the need for such can be demonstrated;
5. (e) any soil penetrations that may be required for providing system foundations necessary for additional structural loading or for providing system trenching necessary for electrical routing shall be done with minimal soils disturbance, with any displaced soils to be temporary and recovered and returned after penetration and trenching work is completed;
6. (f) no concrete or asphalt shall be used in the solar array mounting area other than surface mounted ballasts or other code required surfaces, such as for transformer or electric gear pads;
7. (g) address soil and water resource concerns that may be impacted to ensure the installation does not disturb an existing soil and water conservation plan or to avoid creating a negative impact to soil and water conservation best management practices, such as stimulating erosion or water run-off conditions;
8. (h) there shall be limited use of geotextile fabrics;
9. (i) vegetative cover shall be maintained to prevent soil erosion and plantings shall be native species appropriate to the geographical area, to the maximum extent feasible, consistent with The Vascular Plants of Massachusetts: A County Checklist provided by the Massachusetts Natural Heritage and Endangered Species Program;
10. (j) principles of Environmentally Sensitive Site Design and Low Impact Development Techniques, as defined under 310 CMR 10.04: Definitions, shall be employed;
