The department shall approve a development proposal whenever it finds the following. [PL 1995,
c. 704, Pt. A, §8 (AMD); PL 1995, c. 704, Pt. C, §2 (AFF).]
1. Financial capacity and technical ability. The developer has the financial capacity and
technical ability to develop the project in a manner consistent with state environmental standards and
with the provisions of this article. The commissioner may issue a permit under this article that
conditions any site alterations upon a developer providing the commissioner with evidence that the
developer has been granted a line of credit or a loan by a financial institution authorized to do business
in the State as defined in Title 9-B, section 131, subsection 17-A or with evidence of any other form of
financial assurance the board determines by rule to be adequate.
[PL 2009, c. 293, §1 (AMD).]
2. Traffic movement.
[PL 1999, c. 468, §9 (RP).]
3. No adverse effect on the natural environment. The developer has made adequate provision
for fitting the development harmoniously into the existing natural environment and that the
development will not adversely affect existing uses, scenic character, air quality, water quality or other
natural resources in the municipality or in neighboring municipalities.

A. In making a determination under this subsection, the department may consider the effect of
noise from a commercial or industrial development. Noise from a residential development
approved under this article may not be regulated under this subsection, and noise generated between
the hours of 7 a.m. and 7 p.m. or during daylight hours, whichever is longer, by construction of a
development approved under this article may not be regulated under this subsection. [PL 1993, c.
383, §21 (NEW); PL 1993, c. 383, §42 (AFF).]
B. In determining whether a developer has made adequate provision for the control of noise
generated by a commercial or industrial development, the department shall consider board rules
relating to noise and the quantifiable noise standards of the municipality in which the development
is located and of any municipality that may be affected by the noise. [PL 1993, c. 383, §21
(NEW); PL 1993, c. 383, §42 (AFF).]
C. Nothing in this subsection may be construed to prohibit a municipality from adopting noise
regulations stricter than those adopted by the board. [PL 1993, c. 383, §21 (NEW); PL 1993, c.
383, §42 (AFF).]
D. [PL 1995, c. 700, §6 (RP).]
E. [PL 1995, c. 700, §6 (RP).]
F. In making a determination under this subsection regarding a structure to facilitate withdrawal
of groundwater, the department shall consider the effects of the proposed withdrawal on waters of
the State, as defined by section 361-A, subsection 7; water-related natural resources; and existing
uses, including, but not limited to, public or private wells, within the anticipated zone of
contribution to the withdrawal. In making findings under this paragraph, the department shall
consider both the direct effects of the proposed water withdrawal and its effects in combination
with existing water withdrawals. [PL 2005, c. 452, Pt. A, §3 (NEW).]
G. In making a determination under this subsection regarding an expedited wind energy
development, as defined in Title 35-A, section 3451, subsection 4, or an offshore wind power
project with an aggregate generating capacity of 3 megawatts or more, the department shall
consider the development's or project's effects on scenic character and existing uses related to
scenic character in accordance with Title 35-A, section 3452. [PL 2009, c. 615, Pt. E, §17
(AMD).]
H. In making a determination under this subsection regarding a development's effects on significant
vernal pool habitat, the department shall apply the same standards applied to significant vernal pool
habitat under rules adopted pursuant to the Natural Resources Protection Act. The department may
not require a buffer strip adjacent to significant vernal pool habitat unless the buffer strip is
established for another protected natural resource as defined in section 480-B, subsection 8. [PL
2011, c. 359, §3 (NEW).]
I. In determining whether a developer has made adequate provision for fitting the development
harmoniously into the existing natural environment, the department may consider the effect of at
least 1.5 feet of relative sea level rise by 2050 and 4 feet of relative sea level rise by 2100 as
specified by the department by rule adopted pursuant to section 489-E. [PL 2021, c. 590, Pt. B,
§1 (NEW).]
J. In making a determination under this subsection regarding an offshore wind terminal as defined
in Title 35-A, section 3410, subsection 1, paragraph D, the department shall consider the terminal's
effects on scenic character and existing uses related to scenic character in accordance with Title
35-A, section 3410. [PL 2023, c. 481, §15 (NEW).]
[PL 2023, c. 481, §15 (AMD).]
4. Soil types. The proposed development will be built on soil types that are suitable to the nature
of the undertaking.

[PL 1995, c. 704, Pt. A, §10 (AMD); PL 1997, c. 603, §§8, 9 (AFF).]
4-A. Storm water management and erosion and sedimentation control. The proposed
development meets the standards for storm water management in section 420-D and the standard for
erosion and sedimentation control in section 420-C. If exempt under section 420-D, subsection 7, a
proposed development must satisfy the applicable storm water quantity standard and, if the
development is located in the direct watershed of a lake included in the list adopted pursuant to section
420-D, subsection 3, any applicable storm water quality standards adopted pursuant to section 420-D.
For redevelopment projects only, the standards for storm water management in section 420-D are met
if the proposed development is located in a designated area served by a department-approved
management system for storm water as described in section 420-D, subsection 2, as long as the owner
or operator of the parcel upon which the proposed development will be located enters into or obtains
and remains in compliance with all agreements, permits and approvals necessary for the proposed
development to be served by such management system for storm water.
[PL 2011, c. 653, §18 (AMD); PL 2011, c. 653, §33 (AFF).]
5. Ground water. The proposed development will not pose an unreasonable risk that a discharge
to a significant ground water aquifer will occur.
[PL 1987, c. 812, §§10, 18 (RPR).]
6. Infrastructure. The developer has made adequate provision of utilities, including water
supplies, sewerage facilities and solid waste disposal, required for the development, and the
development will not have an unreasonable adverse effect on the existing or proposed utilities in the
municipality or area served by those services.
[PL 1999, c. 468, §10 (AMD).]
7. Flooding. The activity will not unreasonably cause or increase the flooding of the alteration
area or adjacent properties nor create an unreasonable flood hazard to any structure.
[PL 1987, c. 812, §§10, 18 (NEW).]
8. Sand supply.
[PL 1993, c. 383, §23 (RP); PL 1993, c. 383, §42 (AFF).]
9. Blasting. Blasting will be conducted in accordance with the standards in section 490-Z,
subsection 14 unless otherwise approved by the department.
[PL 2007, c. 297, §2 (NEW).]
10. Special provisions; wind energy development or offshore wind power project. In the
case of a grid-scale wind energy development, or an offshore wind power project with an aggregate
generating capacity of 3 megawatts or more, the proposed generating facilities, as defined in Title 35-A,
section 3451, subsection 5:
A. Will be designed and sited to avoid unreasonable adverse shadow flicker effects; [PL 2021, c.
293, Pt. A, §51 (RPR).]
B. Will be constructed with setbacks adequate to protect public safety. In making a finding
pursuant to this paragraph, the department shall consider the recommendation of a professional,
licensed civil engineer as well as any applicable setback recommended by a manufacturer of the
generating facilities; and [PL 2021, c. 293, Pt. A, §51 (RPR).]
C. Will provide significant tangible benefits as determined pursuant to Title 35-A, section 3454, if
the development is an expedited wind energy development. [PL 2021, c. 293, Pt. A, §51 (RPR).]
The Department of Labor, the Governor's Energy Office and the Public Utilities Commission shall
provide review comments if requested by the primary siting authority.

For purposes of this subsection, "grid-scale wind energy development," "primary siting authority,"
"significant tangible benefits" and "expedited wind energy development" have the same meanings as
in Title 35-A, section 3451.
[PL 2021, c. 293, Pt. A, §51 (RPR).]
11. Special provision; solar energy development. In the case of a proposed solar energy
development, the development will not be constructed within 100 feet of a river, stream or brook. This
subsection does not apply to vegetation removal activities necessary for shade management or road or
utility line crossings within 100 feet of a river, stream or brook.
As used in this subsection, "solar energy development" means a development that uses a solar energy
system consisting of ground-mounted solar panels to convert solar energy to electrical energy and
includes generating facilities and associated facilities.
[PL 2025, c. 106, §1 (NEW).]
