A petition that fails to meet such requirements may be returned to the petitioner, along with a specification of which requirements are not met. In the case of a multiple signature petition, the municipal coordinator may return the petition to the representative petitioner. Where any names on a multiple signature petition are stricken for failure to provide a signature, name, or address within the community, the municipal coodinator may process the petition on behalf of the remaining petitioners, but must notify the representative petitioner.

If an employer requests a copy of the report when making a response to a petition, the municipal coordinator shall also supply a copy of the report to the employer. The municipal coordinator may also provide a copy of the report to any official who has authority to take any action recommended in the report; the petitioner (or representative petitioner) and the employer shall be informed if any such official receives the report.

   1. 1. the signature, name and residential address of the resident;
   2. 2. a copy of the petition and any material filed therewith;
   3. 3. a copy of the municipal coordinator's written response; and

request for review may be filed by more than one resident, if the signature, name, and address of each was included in the original petition. The Department may consolidate requests for review received from more than one resident, provided that notification of each such petition is provided to the relevant employer(s) within five working days of receipt, and that the response to the consolidated petition is made within the appropriate period of time, measured from receipt of the first such petition.

(4) Action by the Department.

1. (a) Release of MSDS(s).

   1. 1. Within five working days of receipt of a municipal coordinator's recommendation that an MSDS be released, the regional office of the Department shall notify the relevant employer(s) and afford the employer(s) an opportunity to respond to the recommendation within four working days. If the employer makes a response, the employer shall simultaneously serve a copy of the response upon the petitioning resident or the representative petitioner of a group of petitioners.
   2. 2. If the employer indicates that there is no objection to the release of MSDS information, the Department shall release such information promptly. If the employer makes no response or indicates any objection, the Department within 15 working days of receipt of the municipal coordinator's recommendation shall determine whether release of MSDS information is appropriate as set forth in 310 CMR 33.06(4)(a)3. When the Department also receives a request to review the municipal coordinator's response, the determination may be delayed until the response required by 301 CMR 33.06(4)(b) is issued.

   3. 3. The Department shall not release MSDS information when, based on particular facts, it finds that:

      1. a. the request is frivolous, or
      2. b. the request is intended to harass the employer(s), or
      3. c. the relevant employer(s) or substance(s) cannot reasonably be identified, or
      4. d. the circumstances on which the petition is based are not rationally related to the release of MSDS information. A written finding stating the Department's determination shall be provided to the petitioner

   (or representative petitioner) and the employer. A statement advising the petitioner (or representative petitioner) of the restrictions on disclosure of the information shall accompany any MSDS released. The Department may assess charges for copying MSDSs on the same basis as charges for copying public records.

2. (b) Review of response of municipal coordinator.

   1. 1. Within five working days of receipt of a request for review of a municipal coordinator's response to a petition, the regional office of the Department shall notify the relevant employer(s) of such request and afford the employer(s) an opportunity to respond to the request within four working days.

   2. 2. Within 15 working days of receipt of such a request for review, the Department shall review such request, MSDS information, the municipal coordinator's written response, any additional information provided by the municipal coordinator or the employer, and any other relevant information. The Department shall prepare a written response summarizing the information considered, the Department's determination of what actions, if any, it will take to alleviate any danger to public health or safety and the reasons for such determination. In making its determination, the Department may, but need not, consider any or all of the following factors:

      1. a. the nature and quantity of the hazardous or toxic substances;
      2. b. the number of people who are being or may be exposed to the substance(s);
      3. c. the proximity of the substance to sensitive populations, public or private drinking water supplies, or other significant potential receptors;
      4. d. the employer's compliance or non-compliance with existing statutes, regulations, ordinances, or by-laws regulating the public health or safety;
      5. e. the Department's authority under existing law;
      6. f. the degree of risk posed by the substance(s), relative to other known public health or safety concerns in the region; and
      7. g. any other relevant factor.
   3. 3. The Department's written response shall be mailed to the community resident (or representative petitioner) who requested the review, the municipal coordinator, and the employer. A copy of the response may be provided to any official who is requested to take action to protect the public health and safety, provided that no MSDS shall be distributed to any such official absent compliance with the requirements of 310 CMR 33.05.
   4. 4. The Department may provide public record information as a part of its response. Such information may be disclosed by the recipient without regard to the provisions of M.G.L.
   5. c. 111F, § 21(b). In any transmittal of M.G.L. c. 111F information together with public record information, the information subject to the provisions of M.G.L. c. 111F, § 21(b) shall be clearly segregated from such public record information, and accompanied by a summary of the restrictions on disclosure of such information provided by said § 21(b).
   6. 5. The Department may take any action authorized by law to protect the public health or safety in response to a request for review. The Department's authority to act under any law shall not be impaired by any failure in making a written response under 310 CMR 33.06 to identify such an action as a measure to be taken to alleviate any risk to public health and safety. A determination that no action is to be taken shall not operate as a bar to any enforcement action under any statute, nor as a release of any claim or right of action based on conditions existing at the time such determination is made.
