discharges:

City of Houston Storm Water Quality (SWQ) Permit: As part of the Texas Pollutant Discharge Elimination System (TPDES), the City of Houston requires an SWQ Permit for certain projects. This permit ensures that stormwater discharges meet local water quality standards.

Harris County Stormwater Quality Regulations: Harris County mandates that all new development and significant redevelopment within unincorporated areas secure a Stormwater Quality (SWQ) Permit before commencing construction. These regulations aim to comply with the county's NPDES or TPDES stormwater permit and protect water quality.
