Industrial Wastewater Contact Information

The Details

What you need

These permits and approvals control industrial-wastewater discharges to the ground, as required by 314 CMR 5.00. 

You must apply for these permits if your facility has a discharge that requires a permit under 314 CMR 5.00 and falls under one of the Standard Industrial Classification Codes listed in the Instructions (see Step 1, below). Any facility without remediation discharges outside of these SIC codes must apply for other groundwater discharge permits, as specified in 314 CMR 5.00. 

Facilities under one of the SIC codes with remediation discharges in accordance with MGL Chapter 21E (the Massachusetts Oil and Hazardous Material Release Prevention and Response Act) are no longer required to obtain an Industrial Wastewater Permit. Applicants may comply under the Massachusetts Contingency Plan, 310 CMR 40.0000.
