July 11, 1995 RE: HAMILTON COUNTYPRISTINE, INC.

Mr. Julian HaywardConestoga-Rovers & Associates Limited651 Colby DriveWaterloo, Ontario, Canada N2V 1C2

Dear Mr. Hayward:

This letter is in reference to the proposed surface water discharge of treated groundwater fromthe Pristine Superfund site. The OEPA Division of Surface Water (DSW) has completedreview of the "Treated Groundwater Discharge Surface Water Modelling" submitted by CRAto the agency on March 24, 1995. Some of the modelling was redone by DSW based oncorrected seasonal flow values and the use of appropriate detection limits to establishbackground levels. DSW then generated effluent discharge limitations. Discharge of treatedground water from the Pristine treatment facility is assumed to continue for 30 years.

Discharge LimitsAttached are the OEPA Discharge Requirements for Pristine to discharge to Mill Creek. Theattachment contains the applicable substantive requirements that must be met by Pristine, aswell as chemical-specific and toxicity limits for the discharge.

Chemical-specific limits for volatile (VOC) pollutants are based on BATT/BADCT (bestavailable treatment technology/best available demonstrated control technology) considerations.All of the remaining 30-day limits, except oil & grease and PCBs, are based onantidegradation requirements. Antidegradation limits are based on an allocation that does notsignificantly increase the background concentrations of these pollutants in the receivingstream.

Oil & grease limits (30-day and maximum) are based upon a Best Professional Judgement ofthe capability of standard oil removal technologies. The PCB limit is based on a mass-balance wasteload allocation to maintain Water Quality Standards (WQS) in Mill Creek.

Maximum limits, when required, are based on inside-mixing-zone-maximum WQS. Maximumlimits are required when the maximum WLA is less than 30 times the average limit.

Mr. Julian HaywardJuly 11, 1995

The acute toxicity limit was set at 1.0 acute toxicity units in order to protect the creek at thenarrative no-lethality WQS (ORC 3745-1-04 and -06).

The polymer additive proposed for use to flocculate iron was not included in the list ofpollutants submitted by CRA. Therefore, the polymer was not included in the wasteloadallocation and does not have a specific discharge limit. However, the Material Safety DataSheet for the proposed polymer (DT-9644, anionic polyacrylamide emulsion) indicates thischemical is toxic to aquatic life with a 48 hour LC50 of 0.33 mg/1 for Daphnia magna.Therefore, care should be taken in the dosing of the polymer into the system to avoidexceedences of the acute toxicity limit.

CRA expressed concern in their June 22, 1995 letter to the USEPA that "the possibility existsthat VOC levels in the influent to the treatment plant may periodically exceed the designinfluent profile due to the variability in ground water conditions at the site." OEPArecognizes the potential for some initial variability and has provided two sets of dischargelimits. The six-month interim limits provide temporary relaxed levels for the three VOCparameters present in the highest concentrations: methylene chloride, chloroform, and 1,2-dichloroethane. Interim limits for these parameters are set at 100 g/1 and 200 f^g/l for 30-day average and daily maximum, respectively. These limits will be in effect for the first sixmonths of operation of the treatment system. This will allow for stabilization of ground-waterinfluent concentrations and optimization of treatment system performance. The second set oflimits takes effect following the six-month interim shake-down period.

The Division of Surface Water tracking system will accept, at most, 30 parameters for eachoutfall number. Due to the large number of parameters to be monitored at this site, eacheffluent limitations table had to be split up into three tables with a different outfall numberassigned to each. It is clearly stated in footnotes to the tables that stations 041 and 042 areactually the outfall 001 discharge.

Waste Load AllocationAlso attached is the Water Quality Assessment from the DSW, which includes waste loadallocations. In the attached memo, DSW explains the criteria for determining waste loadallocation (WLA) values. Two sets of results are presented in Table 3. The first fourcolumns of data present the WLA which would maintain Water Quality Standards (WQS) forMill Creek. The last column presents a WLA performed to determine antidegradation limits.This allocation allows a for a small increase above background concentrations for thepollutants in Mill Creek.

I. Special Conditions (Continued)

"daily concentration limitation" means the arithmetic average (weighted by flow) of allthe determinations of concentration made during the day. If only one sample is takenduring the day, its concentration is the daily concentration. Coliform bacterialimitations compliance shall be determined using the geometric mean.

"30-day load limitation" is the total discharge by weight during any 30-day perioddivided by the number of days in the 30-day period that the facility was in operation.If only one sample is taken in a 30-day period, the weight of pollutant dischargecalculated from it is the 30-day load. If more than one sample is taken during one30-day period, the 30-day load is calculated by determining the daily load for each daysampled, totaling the daily loads for the 30-day period and dividing by the number ofdays sampled.

"30-day concentration limitation" means the arithmetic average (weighted by flow) of allthe determinations of daily concentration made during the 30-day period. If only onesample is taken during the 30-day period, its concentration is the 30-day concentrationfor that 30-day period.

Subject: Water Quality Assessment for the Pristine proposed discharge to MillCreek . : _•

Effluent limits were determined for a propOBed groundwater treatment facilitydischarge from the Pristine Inc. Bite to Mill Creek (Reading, Ohio). Thedischarge was conoidered interactive with General Electric and Shell oil (forseveral parameters they have in common). Limits were determined to maintainthe outside mixing zone average and maximum criteria for the protection ofaquatic life (A£0 using Mill Greek's QJO.IO and Q7|10 stream design flows,respectively. Limits to maintain the human health (HH) criteria for cheaquatic life use and the agricultural water supply (AWS) criteria were basedon the harmonic mean flow. Results were compared to and limited to the InsideMixing Zone Maximum (IMZM) criteria as an upper boundary in the allocationprocess. A separate WLA was performed to determine antidegradation limits.The antidegradation limits are baaed on an allocation that allows for a smallincrease above background concentration for these pollutants. The waterquality criteria and model input data used in the analyses are presented inTables 1 and 2. The WLA results are presented in TabLe 3.
