310 CMR 9.21
Variances
(1) Required Findings. The Commissioner may waive the application of any other section of
310 CMR 9.00 by making a written finding following a public hearing that:
(a) there are no reasonable conditions or alternatives that would allow the project to proceed
in compliance with 310 CMR 9.00;
(b) the project includes mitigation measures to minimize interference with the public
interests in waterways and that the project incorporates measures designed to compensate the
public for any remaining detriment to such interests; and
(c) the variance is necessary:
1. to accommodate an overriding municipal, regional, state or federal interest; or
2. to avoid such restriction on the use of private property as to constitute an
unconstitutional taking without compensation; or
3. to avoid substantial hardship for the continuation of any use or structure existing as
of October 4, 1990, and for which no substantial change in use or substantial structural
alteration has occurred since that date.
(2) Procedure
(a) A request for a variance shall be filed by the applicant prior to publication of the notice
of public hearing pursuant to 310 CMR 9.13(1). The request shall be in writing and shall
include, at a minimum, the following information:
1. an identification of the regulation(s) from which the variance is sought;
2. a description of alternative designs, locations, or construction methods which would
achieve the purpose of the project without the need for the variance;
3. an explanation of why each of the alternatives is unreasonable;
4. an analysis of any detriments to interests of the public in waterways due to the
proposed project and an explanation of how the detriments have been minimized;
5. a description of the measures that will be provided to compensate for any remaining
detriment to public interests in waterways; and
6. a description and supporting documentation of the overriding public interest served
by the project, if applicable; or
7. documentation that the project is a continuation of a use or structure existing as of
October 4, 1990; that there has not been a substantial change in use or substantial
structural alteration since that date; and that application of 310 CMR 9.00 would cause
substantial hardship to the applicant, if applicable; or
8. a legal analysis, with supporting documentation, explaining why application of
310 CMR 9.00 would so restrict the use of private property as to constitute an
unconstitutional taking without compensation, if applicable.
(b) Notice of the variance request shall be published in accordance with 310 CMR 9.13(1)
and shall explicitly indicate that a variance is being requested. The Department shall hold
a public hearing in accordance with 310 CMR 9.13(3) upon which the Commissioner's
findings shall be based. Upon issuance of a variance an adjudicatory hearing is available in
accordance with 310 CMR 9.17.
(c) For projects for which an EIR will be prepared in accordance with M.G.L. c. 30, §§ 61
through 62H, the information required pursuant to the provisions of 310 CMR 9.21(2)(a)1.
through 7., should be included in the EIR if the need for a variance is reasonably foreseeable.
If the variance issue was addressed in the final EIR, the Commissioner shall presume that the
description of alternatives contained therein satisfies the requirements of 310 CMR
9.21(2)(a)2. Notwithstanding this presumption, the Commissioner may require any
modification of the project reasonably within the scope of an alternative within the final EIR.
(3) Commentary. The variance process is intended to apply in the rare and unusual
circumstance where a proposed project satisfies a public interest which overrides the public
interest in waterways but cannot be implemented in a manner which is fully consistent with the
provisions of 310 CMR 9.00; where application of 310 CMR 9.00 would so restrict the use of
private property as to constitute an unconstitutional taking of property; or where application of
310 CMR 9.00 would cause substantial hardship for the continuation of a use or structure
existing as of October 4, 1990. The variance process is designed to ensure that a full
investigation is made to determine whether the proposed project serves an overriding public
interest which outweighs harm to the public resulting from lack of adherence to 310 CMR 9.21
and whether all measures are taken which ensure that detriments to the public interests in
waterways are minimized.
