Proposed Amendments to
Industrial Pretreatment Regulations

Massachusetts Water Resources Authority


MWRA is proposing to amend the following regulations: Sewer Use (360 CMR 10.000). On February 21, 2024, the MWRA Board of Directors authorized MWRA staff to publish notice of the proposed amendments for public comment.

MWRA’s Sewer Use Regulations are required by EPA for its Industrial Pretreatment Program, which is administered by MWRA’s Toxic Reduction and Control (TRAC) department.  The Sewer Use Regulations are derived from EPA’s federal pretreatment regulations found at 40 CFR Part 403, et seq., and set conditions for use of MWRA and municipal sewers, including charges for obtaining and holding a permit.  They also provide for enforcement for noncompliance with MWRA regulations and permits.

These proposed amendments: a) b) c) incorporate changes required by the U.S. Environmental Protection Agency (“EPA”) to bring MWRA’s Sewer Use Regulations in conformance with EPA’s Pretreatment regulations; increase annual charges paid by permit holders; and clean up minor typos.
