Long Term Control Plan (LTCP) and Capacity, Management, Operation and Maintenance (CMOM) Plan

Objective


To develop a plan to separate the remaining combined sewer areas in an effort to lessen the frequency of basement back-ups and other sanitary sewer overflows (SSO's).

Description


Approximately one‐third of the Village of Villa Park is served by its combined sewer system. Since the 1970s, however, the Village has progressively separated its four combined sewer basins, and at present, combined sewers collect direct runoff from only a quarter of the land area within these basins.

The Village’s base wastewater flows from both the combined and separated sewer areas are served by the Salt Creek Sanitary District (SCSD) treatment facility, which has limited capacity for treating wetweather flows. In 1984, the Village completed construction of a relief sewer system and a wet‐weather flow treatment facility (WWFTF) designed to convey and treat ten times average dry‐weather flow (ADWF) during wet‐weather events. While these improvements significantly reduced the frequency and pollutant concentrations of the Village’s CSO discharges to Salt Creek, the need for permitted CSO outfalls has remained.

Justification


The Illinois Environmental Protection Agency (IEPA) has required the Village to report each incidence of a CSO or operation of the WWFTF and has permitted the Village an annual limit of four (4) CSO discharges. However, due to the frequent incidence of large storm events over the past decade, the Village has exceeded this limit in some years. Therefore, as a condition of the WWFTF NPDES permit renewal, the IEPA has mandated that the Village develop a long‐term control plan (LTCP) to reduce the frequency of CSO discharges at its four permitted CSO outfalls within eighteen (18) months of the issuance of the permit.
