Sullins Governor Director Dee Freeman Secretary February 2, 2009 Mr. Bruce Biehl Brenntag Southeast Inc. 2300 East Pettigrew Street Durham, NC 27702 Subject: Review of Engineers Alternatives Analysis Brenntag Southeast, Inc. Discharge to Unnamed Tributary to Third Ford'Creek Durham County Dear Mr. Biehl, This letter concerns issues discussed with you and your representatives in our meeting on January 30, 2009 concerning the Engineers Alternatives Analysis submitted by ARCADIS on the behalf of Brenntag Southeast, Inc dated November 5, 2008. The submittal was submitted in response to the Notice of Violation from this office dated June 23, 2008 and a subsequent meeting with your representatives on August 19, 2008. As we discussed in the meeting, there are still concerns/constraints with: 1) co-mingling of process water and stormwater, 2) volume(s) of stormwater that is conveyed to the treatment units, 3) sample data from the facility indicates that the discharge would not consistently meet the requirements of a stormwater permit without treatment, and 4) there are regulatory constraints with respect to using stormwater permitting mechanism to address wastewater and process control/wastewater treatment units (e.g. pH adjustment and aeration). It is the Raleigh Regional Office position that the facility has an existing illegal (unpermitted) treatment unit, and wastewater discharge. This facility, a bulk chemical re-distribution facility, is required to have an Individual Stormwater permit. Currently, the aeration basins are installed in series and do not appear to be properly engineered for the flow volumes that these units episodically receive. You indicated in the meeting, your intention to separate out the process water and other contaminated water from the stormwater and possibly pursue connection to the City of Durham of the process wastewater that is currently being pumped and hauled. Accordingly, it is the RRO recommendation that you seek out a Special Order by Consent (SOC) to allow the facility to pursue compliance with requirements for permitting activities on site while an enforceable compliance schedule is in place. This tool (SOC) will allow Brenntag to develop and implement an organized approach to affecting full compliance. • One Npr Carolina ,Naturally North Carolina Division of Water Quality Raleigh Regional Office Surface Water Protection Phone(919)791-4200 Customer Service Internet: www.ncwaterquality.org 1628 Mail Service Center Raleigh,NC 27699-1628 FAX (919)571-4718 1-877-623-6748 An Equal Opportunity/Affirmative Action Employer—50%Recycled/10%Post Consumer Paper Mr. Biehl Page 2 Components of this SOC would minimally include the following: -Planning/Investigation -Stormwater Pollution Prevention Plan(SP3) -Stormwater monitoring to include minimally, pH, BOD, metals and organics -Process Water monitoring to include minimally,pH, BOD, metals and organics -Treatment unit monitoring to include minimally,pH, BOD, metals and organics -Discharging treatment unit monitoring -Documentation of Pump and Haul Activities: to include storage control status, storage volume records,pump and hauling records, and destination. -Construction with specific dates to complete portions of the project Attached is an application with directions for submittal.
