I. Definitions.
(a) "Baseline environmental study" means a comprehensive assessment of the existing environmental conditions at the time of application.

II. No permit shall be issued under RSA 155-A:4 for the development of any manufacturing or storage facility over 50,000 square feet unless the applicant submits proof of a completed baseline environmental impact study (EIS). The EIS shall:
(a) Be conducted by a qualified environmental professional or agency approved by the New Hampshire department of environmental services.
(b) Be funded by the applicant.
(c) Include analysis of potential impacts on the following:
(1) Water quality and quantity.
(2) Air emissions.
(3) Soil contamination.
(4) Noise and light pollution.
(d) Include a cumulative impact assessment, considering past, present, and reasonably foreseeable future actions.
(e) Evaluate reasonable alternatives to the proposed action, including a no-action alternative.

(g) Be completed prior to the issuance of any permit.
(h) Be updated every 5 years following the initial study.
(i) Be resubmitted upon any change in ownership or change in use of the facility.
III. The department shall not issue a permit unless it determines that the proposed development will not result in unreasonable adverse environmental impacts, and that appropriate mitigation measures have been identified and incorporated.
IV. All environmental impact studies and related documents shall be made available to the public in accordance with RSA 91-A. The department shall provide a public comment period of not less than 30 days prior to final permit approval.

METHODOLOGY:
This bill requires applicants seeking to develop manufacturing or storage facilities over 50,000 square feet to complete a baseline environmental impact study (EIS) covering air, water, soil, noise, and light impacts. The study must be conducted by a qualified environmental professional or agency approved by the Department of Environmental Services (DES), and the Department may not issue a permit unless it determines the project will not result in unreasonable adverse environmental impacts and appropriate mitigation measures have been incorporated.
The Department of Environmental Services states it does not currently have a program to approve environmental professionals for this purpose, nor does it have existing staff with the combined background necessary to review environmental impact studies addressing air, water, soils, and noise and light pollution. DES notes the criteria for training, practice, and approval of qualified professionals would need to be developed, and the technical review of EIS submissions would require skill sets that do not currently exist within the agency.
To implement the bill, DES indicates that at least two additional full-time Environmental Scientists (19-2040 ENV SCIENTISTS-3 SOC19-06) would be needed. With a September 1, 2026 start date, the estimated cost for both positions in FY 2027 is $150,000, $196,000 in FY 2028 and $200,000 in FY 2029. The Department anticipates these costs would be funded from Other Funds, depending on fee accounts.
The New Hampshire Municipal Association states there will be no impact to municipalities for the EIS preparation costs as any cost incurred would be borne by the landowner.
