A PEL is optional for industrial wastewater dischargers since the Regulation 22 site application process does not apply. The division has limited resources for industrial discharge PELs and may not be able to complete these PELs in a timely manner. Please reach out to the division’s industrial discharge permitting Unit Manager (at erin.scott@state.co.us) prior to applying for an industrial PEL. For industrial facilities that fall under SIC 20, please contact permitting Unit Manager Michelle Delaria (at michelle.delaria@state.co.us) . The division no longer accepts third-party PELs for industrial discharges for review and approval.


 For additional assistance - contact Erin Scott, Unit Manager at erin.scott@state.co.us
