VCM Plant Conoco Chomicals Continental Oil Company P.O.Box 605 Westlake. Louisiana 70669 (318)882-0550 April 13, 1978 Ms. Adlene Harrison Regional Administrator U. S. Environmental Protection Agency Permit and Support jlranch 1201 Elm Street First International Building Dallas, TX 75270 Dear Ms. Harrison: REQUEST FOR NPDES PERMIT REVISIONS - PERMIT NO. LA 0003476 The CONOCO VCM Plant, located in Westlake, Louisiana, is requesting revisions to the existing NPDES Permit. Permit revisions requested are as follows: A. Delete Chromium - Reporting Requirement From NPDES Permit The VCM Plant1is currently required by its NPDES Permit to monitor the cooling tower blowdown stream for chromium. This condition was imposed at the time the facility was using a chromium-type corrosion control treatment. The VCM Plant has since replaced this chromium treatment with a nonheavy metal treatment. The new cooling tower treatment chemicals consist of the following: SCORHIB 1241 - A combination corrosion inhibitor and dispersant. This compound contains organic nitrogen containing compounds, organic synthetic polymers^ polymerized phosphates, organic `phosphorous containing compounds, and other active ingre dients. It does not contain any chromate or any other <heavy metals. TECHNI-SPERSE- A scale inhibitor, antiprecipitant, and dispersant. This A-4 compound is a polymeric blend of organic nitrogen contain ing compounds and other organic dispersants. It does not contain phosphate or heavy metals. ALPHA 520 MICROBIOCIDE A twin-chain quaternary ammonium compound concentrate for the control of algae and bacterial slimes. The cooling tower blowdown is combined with process wastewater and treated in the secondary wastewater treatment system. The Alpha 520 microbiocide is biodegradable at the concentra tions present in the wastewater. \-\ i M|l ''V \ l. f j. f CC 000055a3<r _____ Ms* Adlene Harrison Page 2 April 13, 1978 The VCM Plant is requesting the current requirement for monitoring chromium on the cooling tower blowdown be deleted from the NPDES Permit. Mo chromium compounds are used in the process. It is emphasized that the cooling tower blowdown is discharged to the secondary waste treatment system for treatment. B. Add Discharge From New AcTd-Neutralization Facility The VCM Plant is in the process of installing a vent incineration system as part^of an overall program to comply with the U. S. Environ mental Protection Agency's standard for vinyl chloride emissions (Federal Register, Volume 41, No. 205 - October 21, 1976). Construc tion of the incineration system was begun in September, 1977, with completion projected for October, 1978. A hydrogen chloride absorption column followed by a caustic scrubber will control hydrogen chloride and chlorine emissions from the incin eration vent. A hydrochloric acid waste stream will be produced. A muriatic acid facility will be constructed on plant property to produce an acid product for sales. This facility is expected to be placed into operation in July, 1979. CONOCO plans to install an acid neutralization facility to handle the acid waste stream in the event of a malfunction of the muriatic acid handling facility or if we are unable to move the acid due to a decline in sales (Figure 1). When in operation, the neutralization facility will result in increased wastewater discharges to Bayou Verdine. Since the incineration system will be started up no later than October, 1978, and the muriatic acid handling facility will not be completed until mid-1979, it will be necessary for continuous operation of the acid neutralization facility during that time period. When neutralizing HC1, the acid stream produced in the vent incinera tion system will be pumped to one of two clam shell pits for neutraliza tion. One ofithe clam shell pits will be held on standby and placed in service when t!he other pit requires recharging or maintenance. Vent gases from the clam shell pits will be diverted to a scrubber for re moval of hydrogen chloride. The scrubber water will flow to the clam shell pits for neutralization. The design discharge rates are based on neutralizing 4800 lbs./hr. of HCl (dry weight basis) as a 12 weight percent HCl solution. The wastewater stream from the incineration acid neutralization pits will normally be discharged through a caustic trim neutralization pit and then to a separate monitoring box rather than discharged directly to the secondary waste treatment system monitoring box (Figure 1). These two streams will be combined in a common sewer line that dis charges to the receiving waters. Separate monitoring boxes are required due to the chloride levels present in the acid neutralization stream interfering with physiochemical analyses required for NPDES Permit compl iance monitoring of the waste treatment system. The acid neutraliza tion stream will not be contaminated with any organics from the process. cc* OOOO^BV- Ms. Adlene Harrison Page 3 April 13, 1978 Therefore, with insignificant organic matter present in this stream, treatment in the secondary waste treatment system is of no value. It is anticipated that occasionally additional water may have to be added to the circulation loop fn the bottom of the HC1 absorber for proper temperature control". This will, result in a temporary increase of acidic water being discharged to the clam shell pits. When this occurs, and a low pH is detected, the discharge from the caustic trim neutralization pit will be diverted automatically and combined with the VCM plant process wastewater feed to the secondary treatment system. The combined wastewater stream will flow through an existing caustic trim neutralization pit prior to discharge to the secondary treatment system. If a low pH is not detected when the additional cooling water is temporarily discharged, then the flow will not be diverted to the secondary treatment system. Total Suspended Solids (TSS) Revisions We are requesting TSS concentrations of 60 mg/1 daily average and 135 mg/1 daily maximum for the new acid neutralization pits' discharges. - These are the permissible levels required in the publication "EPA .Development for Major Organic Pollutants," April, 1974. TSS analyses conducted on an existing inplant acid neutralization pit indicated levels of 75 mg/1 daily average and 181 mg/1 daily maximum as typical for that type of system. However, since the calculated flow through the new acid neutralization pits will be less than one-half the flow through the existing acid neutralization pit, fewer solids should be washed out , of the new pits. This is the basis for assuming the EPA guidelines may be achievable. It is emphasized that we have no data available for a neutralization system with similar flows for comparative purposes and we can currently only assume, on the basis of the limited data availa ble, that the EPA's permissible levels can be achieved. Once the system is operational, and we find these TSS levels are not attainable, then we will approach the Louisiana Stream Control Commission and EPA with a request for relaxation of the permit TSS limits. We are requesting revisions to our NPDES Permit for increasing the per missible TSS discharge limitations as follows: Current Permitted TSS Discharge Levels New Acid Neutralization Pit Dis charge TSS Levels (Projected) Daily Average Lbs./Dpy 558 ___ 55(a) Daily Maximum Lbs./Day 1,256 123(b) Requested TSS Discharge Levels 6.13 1,379 ia) 60 ppm at 76 gpm b) 135 ppm at 76 gpm 0005sS3 Ms. Adlene Harrison Page 4 April 13, 1978 C. Requested Revisions to NPDES Permit Limitations and Monitoring Requirements Proposed sample points and permit parameters are as follows: 1) Acid Neutralization PH Weir Box (VCM ID Discharge No. 1, Figure 1) a) Continuous Flow Measurement/Recording 2) Waste Treatment System Weir Box (VCM ID Discharge No. 2, Figure 1) a) BODs b) COD c) Ammonia (as N) d) Chlorinated Hydrocarbons (as Ethylene Dichloride) e) Continuous Flow Measurement/Recording NOTE: pH/temperature monitoring instruments relocated to VCM ID Discharge No. 3. 3) Combined Waste Streams Monitoring Box (VCM ID Discharge No. 3) New EPA 001 Outfall a) Continuous pH Measurement/Recording b) Continuous Temperature Measurement/Recording c) Total Suspended Solids (TSS) These monitoring point locations are required due to the chloride con centrations that will be present in the acid neutralization pit dis charge. The chlorides will interfere with physiochemical analyses re quired for compliance monitoring on the, waste treatment system. Monitoring of the combined streams has been incorporated where possible. A single discharge point, EPA Outfall No. 001, is being requested for compliance reporting. The combined waste streams (secondary waste treat ment and acid neutralization pit discharges) are discharged at this point. The permissible TSS discharge levels will be obtained by using the combined flows of these two streams and calculating the TSS loading on the basis of a single sample of the combined streams. Other para meters required for compliance monitoring of the waste treatment system will be measured at the waste treatment system weir box; loadings will be calculated using the flow from the waste treatment system. Continuous pH and temperature measurements will be made on the two combined waste streams prior to discharge to the West Drainage Ditch. A summary of the requested effluent limitations and monitoring require ments is presented in Table 1. The changes requested consist of dele tion of the chromium-reporting requirement, increasing the TSS dis- CCR 000055839 Ms. Adlene Harrison Page 5 April 13, 1973 charge limitations, and the establishment of new monitoring locations.
