Summary
Colorado administers stormwater discharge permits statewide through the Colorado Discharge Permit System, requiring construction sites and industrial activities to obtain coverage before discharging runoff to state waters.
(2) The division shall examine applications for and may issue, suspend, revoke, modify, deny, and otherwise administer permits for the discharge of pollutants into state waters and for the use and disposal of biosolids. Such administration shall be in accordance with the provisions of this article and regulations promulgated by the commission. Until modified pursuant to this article, final permits shall be governed by their existing limitations.
Full Breakdown
Under the Colorado Water Quality Control Act, CRS 25-8-101 et seq., the Water Quality Control Division issues general and individual CDPS permits for stormwater associated with construction activities disturbing one or more acres, industrial facilities, and municipal separate storm sewer systems. Permittees must prepare a stormwater management plan, install best management practices, conduct routine inspections, and maintain records. The state permit program is delegated under the federal Clean Water Act and applies uniformly across Colorado regardless of local jurisdiction.
Violations & Penalties
Discharging without a permit or violating permit conditions can result in administrative penalties up to $10,000 per day and civil penalties through enforcement actions by the state.
