BACKGROUND, ANALYSIS, AND ALTERNATIVES IDElmFIED • The Environmental Protection Agency requires that the lr.dustrial Pretreatment Program be regulated by the Wastewater utillty Ordinance. The City must re-evalu110 Its dls.:harge ilmltatlon requirements for Industrial Users every five years . The new !imitations are required to be lncolJJO(llted Into the Wastewater Ordinance . • The local limlts are developed to control the level of pollutants which are discharged from Industries and enter Imo the sanitary sewer system and ultim91ely enter the wastewater treatment plant. The wastewater treatment plant is regulated by the Colorado Depar,ment of Health and Environment and the EPA by the NPDES permit. The plant must maet specific standards which are outlined In the NPDES permit . Setting local llmlts helps to protect 'NOrl<er heallil and safety , wastev,ater plant processes, sludge and the receiving stream . The EPA has received a copy of the amendments proposed by the City of Englewood , public noticed the changes , and approved t he proposed amendments. Improper Implementation of the Pretreatment Program is a violation of the l1E 'NWTP NPDES permit. Consequences of not implementing the regulations could include EPA fining the City up to $25 ,000 per day . FINANCIAL IMPACT There will be no direct financial impact on the City by adopting the proposed amendments to the Wastewater Utility Ord ina nce .
