Summary

HP Hood received planning board approval to build a 4,800 sq ft wastewater pretreatment facility at its North State Street site to reduce biological oxygen demand before discharge; the board granted waivers and required final state/federal permits as precedent conditions.

Nobis Group and HP Hood presented plans for a 4,800-square-foot wastewater pretreatment building and associated tanks at 330 North State Street, designed to reduce the plant’s biological oxygen demand (BOD) before discharge to the city collection system. The application calls for covered tanks (equalization, recirculation, MBBR and sludge holding) and an aerobic process housed inside the building to limit odors and volatile byproducts.

Planning staff found the application complete and recommended waivers to permit acceptance and public hearing the same evening. The board granted the waivers, architectural design review and then major site-plan approval with precedent conditions that require applicants to secure all required state and federal permits prior to final sign-off. Hood representatives and engineers emphasized that the process is aerobic and that tanks are covered; they said the facility will not produce fermentative biogas and that typical odors would be "earthy" and mitigated by covered equipment and process controls.

The board attached standard precedent and subsequent conditions, including documentation of required state environmental permits and a requirement to meet staff screening and operational conditions. The project sponsor said the installation responds to regulatory direction from the sewer authority to reduce BOD inputs to the city’s wastewater-treatment system.
