Stormwater Quality (SWQ) Permit for Construction Activities

Developers & Builders Operating within unincorporated Adams County MS4 permitted area

Per Adams County Development Standards and Regulations; all developers and builders within unincorporated Adams County Municipal Separate Storm Sewer System (MS4) permitted area are required to obtain an Adams County Stormwater Quality (SWQ) Permit for land disturbance activities equal to or greater than one acre, or for land disturbance activities less than one acre that are part of a larger common development.

SWQ Permit 

The intent of the SWQ permit is to ensure that developers and builders are in compliance with state and federal stormwater regulations for construction activities. The county's goal is to provide compliance assistance and aid in preventing the potential for State and EPA enforcement fines due to violations of stormwater regulations governing construction site operators.

Failure to obtain a SWQ permit for applicable projects will result in delays in the issuance of grading, right of way and/or building permit. Developers and builders should therefore plan ahead when preparing to apply for construction permits that may require an associated SWQ permit.
