General Subject: 2013 DMR Discharges of Selenium for SCGENCO/Williams Ash Disp Hw52 - Moncks Corner, 

SC. NPDES Permit SC0046175.

TOPICS DISCUSSED AND ACTION TAKEN

I called Ms. Rippy at 3:30 pm on 4/29/2015 to confirm DMR discharges of selenium for the facility and request 

copies of the current and previous permit. Ms. Rippy confirmed that selenium is not included in the current 

permit, issued August 30, 2013 and effective October 1, 2013. The facility was required to monitor for selenium 

in the previous permit.

Ms. Rippy speculated that most likely, SC DHEC determined that there was no reasonable potential to

contribute to impairment of the receiving waters, and therefore, no monitoring requirements or permit limits 

were set for selenium in the current permit. Ms. Rippy said she would email the current effective and previous 

permit and ask the permit writer about the rationale for selenium monitoring requirements.

I received the permits and permit rationales from Byron Amick, permitting engineer, (803-898-4236, 

amickbm@dhec.sc.gov) by email on 4/29/2015. See correspondence below.
