SB 644 New Hampshire Senate · 2026 Regular Session

requiring background checks for solid waste and hazardous waste facility owners.

SB 644 requires background checks for individuals seeking permits to operate solid waste and hazardous waste facilities in New Hampshire. Specifically, it mandates criminal history checks - including fingerprint-based national database searches - for owners, officers, directors, partners, and managers of these facilities during the permit application process. The law applies to all facility owners (including partners in partnerships and managers/members in LLCs) and covers both new permits and ownership transfers. These checks must be conducted through the state police and FBI databases, with applicants submitting authorization forms and fingerprints to the Department of Environmental Services.
