To the Division of Water Quality:
CDM Smith Inc., on behalf of Cumberland County(County), is submitting two copies of the
Stormwater Discharge Monitoring Report for Outfalls 1-4.Samples collected from outfalls during the
January 1-June 30, 2016 semi-annual sampling event had detections of total suspended solids
(Outfalls 1 and 2) above the benchmark values. In response to the benchmark value exceedances,the
County implemented a Tier 1 response.
Samples were collected from Outfalls 1, 2, and 4 on February 16,2016. No flow was reported at
Outfall 3.Samples collected from Outfalls 1 and 4 were analyzed for chemical oxygen demand,fecal
coliform, and total suspended solids.Samples collected from Outfall 2 were analyzed for pH,oil &
grease, and total suspended solids.Total suspended solids concentrations were 110 milligrams per
liter(mg/L) in Outfall 1 and 294 mg/L in Outfall 2. No other detections exceeded the benchmark
values.
Per the Tier I response requirements, a stormwater management inspection of the facility was
completed on March 15,2016 in order to identify the potential for improvements to reduce
concentrations of total suspended solids.The County will maintain a record of the Tier 1 response and
monitoring results at the landfill.
