GENERAL SUBJECT : Discharges Reported to DMR in 2008



### TOPICS DISCUSSED AND ACTION TAKEN

I called MPM Silicones on June 29, 2010, to speak with Fred Dailey regarding specific discharges from the facility reported to DMR in 2008. I left him a message ident ifying myself and the reason why I was calling. I asked him to return my call or forward my information on to the correct contact. Jason Martin returned my cal l at 9:00 am on Wednesday, June 30. I told Mr. Martin that I wanted to confirm the nickel, copper, hexachlorobenzene (HCB), and benzo(a)pyrene (BAP) conc entrations for Outfall 001 reported to DIMR in 2008. Mr. Martin stated that each pollutant is reported quarter ly, expect for BAP which is only required to be reported annually.

The following tables show the original data reported to DM R in 2008 and the correct data provided by Mr. Martin. Mr. Martin confirmed that all of the concentra tions were reported as μg/L, but were entered into the database as mg/L. Other errors included missing BDL indica tors and incorrect concentration values for copper, HCB, and BAP. Mr. Martin also stated that there shoul d only be one yearly concentration value for BAP as it is reported annually. The corrected table also shows now conc entration values for copper and nickel in the second reporting period. Mr. Martin stated that no sample was co llected due to a sampling error. The error should result in NODI Code E, G, or 8 being submitted. I told him that th e database would be corrected to reflect the data he provided.
