Lawmakers refine landfill rules: net-benefit review, third-party assessments and leachate plans considered

Representative- and agency-led discussions in the House Environment & Agriculture Committee’s Solid Waste Subcommittee this week focused on tightening how New Hampshire reviews proposed new landfills and on strengthening operators’ leachate-management plans.

A trio of bills under consideration would: (1) create an initial screening step for landfill permits that requires DES to determine whether a "net public benefit" exists before a full technical review; (2) allow DES to accept and evaluate pending applications for completeness during a moratorium without triggering automatic approval; and (3) require more-detailed leachate-management plans and contract disclosures from applicants.

DES Waste Division Director Mike Wimsatt advised the subcommittee multiple times during the session. On the two-stage review he told members that "if changes in policy through law or administrative rule were made during that time, it would be necessary for the landfill applicant, permit applicant to amend the application." Wimsatt said the department commonly consults with other agencies and recommended language allowing DES to consult the Departments of Transportation, Business and Economic Affairs, and Natural and Cultural Resources when evaluating traffic, economic and tourism impacts associated with a proposed site.

Representative Peter Germana led drafting of the amendment to HB215 (landfill net-benefit review). The amendment would require an independent third-party assessment paid for by the applicant and requested by the host community (or other abutting municipalities). Applicants must submit at least three independent contractor candidates; DES would vet qualifications and, if the parties cannot agree, the commissioner would pick a contractor from the list after a 60-day window. The proposed bill text defines "net public benefit" as present when "potential benefits for a proposed project are determined to be greater than the potential harms" and lists harms (health, property-value, tourism and wildlife impacts) and benefits (capacity need, local economic benefits and infrastructure improvements) to guide the evaluation.

Subcommittee members debated whether that initial determination should be appealable and heard DES advise the appeals already exist through the state’s Waste Management Council for department decisions. Representative Germana said the amendment is intended to give DES an early stage to filter out proposals that would not produce a net benefit before investing in full technical review.

On HB171 (a temporary moratorium on new landfill permits), members discussed language changes recommended by Director Wimsatt to allow DES to receive applications and evaluate them for completeness during the moratorium but not to proceed to a substantive review that would trigger statutory timelines or automatic approvals. Wimsatt told the panel the "notwithstanding" language is necessary because current RSA provisions can cause an application that is not acted on within a set period to be deemed automatically approved; the amendment would create an exception for the moratorium period.

On HB566 (leachate management), Representative Germana presented amended language that would require applicants to include a detailed long-term leachate-management plan in permit filings: how leachate is collected, any on-site treatment, storage, transportation off-site, destination/treatment facility and a projected frequency of transports, plus contingency plans and contract details for leachate handling. Members pressed whether the bill should require evidence of multiple disposal outlets; DES staff and an operator from a turnkey facility said existing rules already require at least two contracted outlets, and in practice operators identify multiple contingencies. The amendment’s author said the bill moves some contract-related items into the required plan rather than trying to force long-term contractual terms into statute.

What the committee did - Subcommittee members indicated consensus to have sponsors send drafted language to OLS for HB215 and HB171 and to forward amended versions to the full committee’s executive session once OLS restores any omitted statutory sections. - On HB566 the subcommittee asked sponsors to continue refinement; the sponsor planned to circulate updated language to colleagues and to the chair before executive session.

Why it matters New Hampshire law requires the state to ensure adequate solid-waste capacity while also protecting public health and natural resources. These bills aim to add earlier-stage screening and outside expertise so DES and host communities can evaluate where benefits outweigh harms — and to tighten permitting details (for example, leachate plans) so reviewers and the public have clearer information earlier in the process.

What remains unresolved Members asked whether the first-stage net-benefit decision should explicitly reference an appeal route; DES said department decisions are appealable to the state Waste Management Council and that the written denial/approval letters should reference appeal rights. Sponsors and staff also flagged drafting fixes (some omitted sections by OLS) and asked OLS to reinsert original statutory material before the bill is scheduled for executive session.

Next steps Sponsors said they will work with the director and OLS to finalize amendments and bring the bills to the committee’s executive session. The subcommittee did not adopt final statutory text; members asked that OLS restore omitted sections and that sponsors circulate the redraft to members in advance of the executive session.
