Answers from the rulebook for Town of Hamlin

Town of Hamlin’s own rules

  • Who permits septicMixed (with conditions)

    Subsurface wastewater (septic) systems on land inside Hamlin town. The town appoints the local plumbing inspector (LPI) who issues septic permits and inspects; the state Subsurface Wastewater Disposal Rules (10-144 CMR ch. 241) set the standards.

    • Hamlin's municipal officers must appoint a plumbing inspector under 30-A §4221(1); the LPI investigates complaints about subsurface wastewater disposal under §4221(3)(g).
    • The LPI enforces state subsurface rules; the state Maine CDC rule text was not opened in this run (PDF text unavailable), so the rule's own wording and current version were not verified.
    • Hamlin's appointed LPI was not identified; no official Hamlin page names the current inspector.
    “in every municipality, the municipal officers shall appoint one or more inspectors of plumbing, who need not be residents of the municipality for which they are appointed.”

Rules another office applies inside Town of Hamlin

Town of Hamlin does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.
