Combustion, Inc. SiteRemoval Action

1 - INTRODUCTION

1.1 Background

The Combustion, Inc. site is located in Livingston Parish,Louisiana about three miles northeast of Oenham Springs. The site,which operated from the 1960s until 1982, consists of a smallinactive oil reclamation plant (Process Area) and a separate areathat contains fourteen shallow ponds (Pond Area) - The generalvicinity of the site is depicted in Figure 1-1.A two-phase cleanup (Removal Action) is currently being planned forthe Combustion, Inc. site. Phase I of the cleanup will includeremoval and proper disposal of the aboveground and undergroundtanks and their contents, above ground structures, the pipelineconnecting the Process Area to the Pond Area, and the oil on thesurface of the ponds. Phase II of the cleanup will address thewater, solids and any affected soils in the Pond Area.The existing water inventory at the site, along with any wastewateror contaminated storm water generated during the cleanup processmust be treated prior to discharge. This plan characterizes thewater currently at the site, describes the existing pond stormwater treatment system, and outlines steps necessary to ensureproper treatment of the wastewater and storm water generated in thePhase I and Phase II cleanup activities.1.2 Objective and ScopeThe objective of this plan is to characterize the wastewater at theCombustion, Inc. site and to define the method for treatment -Specifically, the scope of this plan includes the following:

o Characterization of wastewater currently on siteo Description of the existing pond wastewater treatment

systemo Characterization of the existing effluent,o Specification of upgrade requirements for the existing

wastewater treatment system,

2 - PRESENT SITE CONDITIONS2.1 Existing Wastewater InventoryThe existing wastewaters at the Combustion, Inc. site are containedin tanks at the Process Area and in tanks and ponds at the PondArea. Layouts of the Process Area and Pond Area are provided inFigures 2-1 and 2-2, respectively. Approximate Wastewaterinventories for the Process Area and Pond Area are provided inTables 2-1 and 2-2, respectively. The inventories are developedfrom data presented in the Preliminary Remedial InvestigationReport for the site*2.2 Existing Inventoried Wastewater CharacteristicsExisting waters at the site were characterized in the PreliminaryRemedial Investigation. The analytical results of individual tankand pond water samples are provided in Appendix A and summarized inTable 2-3-2.3 Existing Wastewater Treatment SystemThe wastewater treatment system currently in operation at theCombustion, Inc. site treats storm water runoff contaminated by oilor oily wastes. A schematic of the existing system is provided inFigure 2-3.Additional wastewaters are continually generated at the site as aresult of the containment of storm water runoff at the site. Rainfalling on the western half of the Process Area is contained bycontaminant dikes, sumps and/or the natural topographic relief.The contained runoff is transferred to Tank l within 24 hours viaa manually operated pump. Tank 1 allows time for oil/waterseparation, provides some equalization capacity and generally actsas a temporary storage tank until the runoff can be routinelydrained to the Pond Area. An underground pipe from Tank 1 to PondC facilitates this transfer by gravity.The Tank 1 storm water flows through Ponds C, B and A, which serveas gravity oil/water separators to a Drainage Ditch running eastthen north along the perimeter of the Pond Area. The DrainageDitch discharges to Pond M, which is connected to the final pond,Pond N. The Drainage Ditch and Ponds M and N allow facultativebiological degradation ( i . e . , by aerobic and anaerobic organisms)

of -the soluble organics in -the wastewater- The -treated wastewateris discharged from Pond N to the stream located west of the site.Rain falling on the Pond Area is contained within the ponds. Theponds are interconnected and the collected water is eventuallytreated and discharged via the outfall from Pond N.As shown in Appendix A, the data collected during the 1989 RemedialInvestigation showed the BOD concentration in Pond N water to be33 Kg/L and the BOD in Pond C water to be 140 mg/L, The 76% BODremoval is indicative of biological degradation of the solubleorganics in Ponds C, B A, the Drainage Ditch and Ponds M and N.2.4 Existing Effluent CharacteristicsDuring 1988 the effluent discharged from Pond N was sampled at theoutfall to the stream west of the site for the eight months when adischarge flow occurred. The analytical results of this effluentcharacterization were reported in the Preliminary RemedialInvestigation Report. The analytical data is provided in AppendixB and is summarized in Table 2-4.2-5 Existing Wastewater Flow RatesThe average annual flow through the treatment system is estimatedto be approximately 16 gallons per minute. This estimate is basedupon the mean annual rainfall rate for Baton Rouge during theperiod 1942 to 1981 (approximately 57 inches per year). TheRational Method was used to calculate runoff assuming a runoffcoefficient of 85% and evaporative losses based up on an annuallake evaporation rate of 48 inches per year from ponds without asurface oil layer (Ponds A, D, E, I, 3, K, L, M and N ) . The basisfor the average annual wastewater flow rate is provided in Table2-5.The actual rate of outflow from Pond N is restricted by thediameter of the discharge pipe. During heavy rainfall, the inflowrate may be a greater rate than the discharge rate; therefore wateris temporarily stored in the pond system. _ The pond waterelevations rise as the water "backs up" in the system.

3 - PROPOSED TREATMENT SYSTEM UPGRADE

The site cleanup may potentially result in surge flows ofrelatively high strength wastewaters. These surges would likelyoverwhelm the existing facultative pond system because of the lackof process control and the limited oxygen transfer characteristicsassociated with a pond treatment system. This section describes anupgrade of the pond system to assure consistent treatment of futuresite wastewaters.3*1 Basic System UpgradeThe core of the system upgrade will consist of adding a packagewastewater treatment system to the existing flow scheme. Aschematic of the system is provided in Figure 3-1- The retentiontimes for the system components, at an average flow rate of 16 gpm,are provided in Figure 3-1.The package system will be an extended aeration activated sludgedesign. A design data sheet for the package treatment system isprovided in Table 3-1- Preliminary process flow schematics arepresented in Figures 3-2 and 3-3- A more detailed schematic willbe available to LDEQ and EPA once a package wastewater treatmentsystem vendor has been selected-3.2 Anticipated Wastewater CharacteristicsWastewater generated during the Removal Action is not expected todiffer greatly in specific chemical composition from the wastewatercurrently present at the site. Wastewater generated from physical/chemical treatment of oily emulsions is, however, expected to havehigher organic strength as expressed by increased TOC and BODlevels.Anticipated wastewater characteristics for the Phase I RemovalAction also are provided in Table 3-1- These concentrations weredeveloped by assuming that the inventory in Ponds A, B and C werereduced sufficiently to accommodate the volume of water from theProcess Area tanks. The concentrations were then calculated froma flow weighted average of the loadings in these three ponds.The anticipated wastewater characteristics provide a design basisfor the proposed treatment system upgrade. All discharged effluentwill meet the LDEQ effluent discharge limits presented in Section4.0.

3.3 Basic System SetupThe package wastewater treatment system will be located in the PondArea in the vicinity of Ponds M and M. The system will be placedupon either wooden crane mats or a reinforced concrete pad. Asmall pump will be used to divert the current flow route (Pond M toPond N) through the package treatment system- Power hookups forpumps and airblowers will be made available in the Pond Area. Theinstallation of the treatment system, and any additional equipmentor surface transfer piping, will be the responsibility of vendorsupplying the package Plant-3,4 Initial System OperationUpon initiation of the Phase I cleanup, the current pond waterinventory will be reduced so that the Pond Area can accommodate adesign storm of 24 hours duration and a return frequency of 25years (equivalent to 9.5 inches rainfall). The surcharge from thisstorm is estimated to require an inventory reduction of 1.7 milliongallons. The inventory of each pond will be reduced in proportionto its current capacity. The water removed from each pond will bepumped to the package wastewater treatment system (via Pond M) fortreatment- Treatment of this volume of water over a forty-five daytime period will require a round-the-clock flow of 43 gallons perminute. The basis for this flow rate is presented in Table 3-2-The gravity flow system between ponds will be the primary measuresof achieving this volume reduction. Portable pumps and piping willbe used to permit water transfer should the water levels drop belowthose required for gravity flow. The pump and piping will also beused if there is any danger of oil carryover between ponds.3.5 Basic System OperationWater from the Process Area tanks will be transferred either toTank 1 by a portable pump and piping or directly, to Pond c via avacuum truck. Water from Tank 1 will be gravity-drained to Pond Cvia the underground pipeline currently used for storm watertransfer. The integrity of the stonnwater transfer pipeline willbe proven by low pressure testing prior to use during RemovalAction activities. (The testing procedures are provided in thePhase I Removal Action Work Plan.) Water from the ponds or tanksin the Pond Area will either drain by gravity or be pumped to PondsC, B and A. The waters in these ponds may be recirculated prior to

=42.6 gpm

discharge to the Drainage Ditch if additional retention time isrequired for oil/water separation or equalization. Floatingcurtains will be placed near the discharge pipe from Ponds A and Mas an additional safeguard against the unlikely event of oilcarryover. A surface oil layer is not currently present on Pond M.

A floating curtain or rigid baffle structure will be installed inPond B to prevent the oil in Ponds B and C from being discharged toPond A and the Drainage Ditch downstream- There will be no activeflow in Ponds B and C during the removal of oil from those ponds.During the removal of oil from Ponds B and C, the Process Areastormwater will be retained and the transfer pipeline shut off orthe flow will be released offsite if the Process Area cleanup iscomplete.The Drainage Ditch and Pond M provide time for some facultativebiological-treatments prior to the package treatment system. ThepH of the water from each pond will be adjusted to within a 6,0 to9*0 range before discharge to the Drainage Ditch. This form ofbatch pH adjustment will be achieved by adding pH-adjustingchemicals to the water and recirculating the flow until the targetpH is achieved.The package system basically consists of an aeration tank followedby a clarifier unit. The clarifier unit provides control over thebiomass in the system thus giving a more reliable operation thanthe existing pond system, particularly if there is a potential forincreased loadings to the system- Mechanical air blowers will beused to introduce ambient air into the aeration tank in order toprovide the oxygen needed for the degradation of the varyingorganic loads.The average flow rate of 16 gpm (developed in Section 2.5) providesfor a hydraulic retention time of two days. The system willtypically be operated at the average flow rate. However, duringthe initial inventory reduction, described in Section 3 . 4 , a flowrate of 43 gpm will be employed- This inventory reduction flow(developed in Section 3.4) results in a hydraulic retention time of0-7 days-The package treatment system will be operated at a minimum sludgeage of approximately 20 days. This long sludge age reduces theamount of biosolids generated by the system and eliminates the needfor sludge digestion. Based upon the anticipated BOD loading,sludge generation is expected to be less than 90 Ibs/day of dry


solids. Waste activated sludge from the package treatment systemwill be discharged to a portable tank for gravity thickening.Waste solids are expected to amount to no more than four dry tonsduring the Phase I Removal Action (assuming a 90-day projectduration). The solids will ultimately be returned to Pond M fortreatment and disposal along with the solids already present inPond M.The treated effluent from the package plant is to be discharged toPond M for final effluent polishing- A small concrete pad will besubmerged below the .package plant discharge pipe in order toprevent scouring of the pond bottom during discharge to Pond M.The water from Pond H will be discharged onsite to a small ditchrunning from Pond N to the stream located west of the site. Thesmall -ditch will be formed by removing the existing Pond Ndischarge pipe.The discharge from Pond N will occur on a batch basis during start-up and Removal Action activities and on a continuous basis duringnormal site conditions, i . e . , when no Removal Action activities areoccurring. Effluent monitoring will occur from within Pond N forbatch discharge conditions and at the discharge from Pond N to thesmall ditch for continuous discharge conditions. Initial testingwill be performed to demonstrate that leaching of constituents fromthe sludges in Pond N, if occurring, does not impact the effluentquality between the time when a batch is sampled until the time thebatch is actually discharged. The IiDEQ effluent discharge limitsare presented in Section 4.0,3 . 6 Wastewater Pretreatment and Post-Treatment OptionsThe package treatment system is designed to meet the LDEQ treatmentstandards in Section 4.0, however, optional pretreatment and post-treatment process options can be implemented, when necessary, inorder to maintain the performance of the wastewater treatmentsystem during any cleanup activities. Potential process optionsare listed in Table 3-3, The criteria and conditions by whichpotential process options will be implemented are included in Table3-3.The long retention times in the system means that any of theoptions listed .could be implemented, as appropriate. It isanticipated that these process options are available as skid-mounted units for ease of transportation and installation.

During removal action activities, the metals in the water phase inPond B may be treated by in situ precipitation, if necessary, priorto discharge to Pond A. The sludge generated as a result of thistreatment step would be managed along with the existing Pond Bsolids inventory. The remaining site water will be treated at thepackage treatment system as described in Section 3.5.3.7 Air EmissionsDuring Removal Action activities the influent wastewater to Pond Mwill be analyzed for benzene, toluene, ethylbenzene, and xylenes(BTEX) compounds. The monitoring frequency is provided in Table 4-2. Concurrent with this monitoring, daily air monitoring for BTEXcompounds will be performed in accordance with the Air -MonitoringPlan. Corrective measures will be implemented if the BTEXwastewater concentrations increase along with a correspondingincrease in BTEX air emissions above their respective actionlevels. The initial response will be to reduce the wastewater flowto the treatment system in order to reduce the potential for airemissions. If air action levels continue to be exceeded, thesource of the elevated BTEX levels will be determined and sourcecontrols evaluated and implemented, if necessary ( e . g . , activatedcarbon).3.8 Contingency PlanDuring possible process interruptions, the discharge from Pond Nwill be shut off while the process performance is evaluated- Ifnecessary, the water from Pond N will be returned to one of theponds still in service. Sufficient capacity will be available dueto the initial inventory reduction described in Section 3,4- Thelong retention times in the pond system, in addition to flowrecycling, if necessary, should provide enough time to remedy thepackage plant operation or install additional or replacementprocess options, such as those described in Section 3 . 6 .

4 - EFFLUENT LIMITS. MONITORING AND REPORTING

4.1 Effluent LimitsDuring the past four years of daily site inspections, there hasbeen no observable off-site impact from the discharge of Pond N tothe stream located west of the site. This discharge was sampledroutinely during 1988 and the analytical results are summarized inTable 2-4. A summary of the analytical results for the pond andtank water samples for the 1989 Remedial Investigation is presentedin Table 2-3. A comparison of the relative levels of the para-meters in Tables 2-3 and 2-4 showed that site constituents weregenerally not being discharged to the stream.The purpose of the upgraded treatment system described in Section3,0 is to ensure that the historical quality of the discharge fromthe Combustion, Inc. site is not diminished as a result of sitecleanup activities. The LDEQ effluent discharge limits areprovided in Table 4-1.4.2 Monitoring SystemThe performance of the wastewater treatment system will bemonitored to ensure that the quality of the discharge is, at aminimum, being maintained, if not improved upon. The parametersfor analysis and the frequency of monitoring are provided in Table4-2. Analyses will be performed in accordance with approved EPAmethods for wastewater analysis.
