DEHNR /:;.2 --;"! ~ RE: Post Closure Plan Modification Request dated February 21, 1997 Central Transport, Inc. Facility, Charlotte, NC, EPA ID# NCD 046 148 540 Dear Mr. Simpson: This office is in receipt of Central Transport, Inc's (CTI) February 21, 1997 request to modify the January 1991 Post Closure Plan. The review of the modifications proposed in the February 21, 1997 correspondence and material previously submitted by CTI raises several issues. These issues must be addressed prior to approval of a modification to the Post Closure Plan. The Hazardous Waste Section's (HWS) response is organized such that each of the eight items raised by CTI will be addressed in the same order as set forth in the February 21, 1997 correspondence. 1. Prior to approval of a modification of the monitoring well network, the ground-water flow direction at the site must be defined. CTI has submitted several different interpretations of ground-water flow at the site. In the February 29, 1996 Post-Closure Groundwater Monitoring Annual Report, CTI has indicated that the ground-water flow is in a south-southeasterly direction (see figures 4-1, 4-2, 4-3, and 4-4). In the February 5, 1996 RCRA Post-Closure Permit Application (Application), Figure E-2 indicates that ground water flows to the east on the west side of the on-site stream and to the west on the east side of the stream. In figures E-4, E-5, E-6, and E-7 of the same application, the ground water flows to the south-southeast. Figure 7 of the 1991 Post Closure Plan indicates that ground-water flow on the west side of the stream is to the east and ground- water flow on the east side of the stream is to the west P.O.

Mr. Glen Simpson May 28, 1997 Page 2 of3 2&3. Request to reduce the analyte list: CTI may resubmit their request to reduce the parameter list once the ground-water flow direction has been determined. The request must include a rationale for deleting each constituent. These reasons may include, but are not limited to: a) the constituent cannot be associated with any activities at the site; b) the constituent is not above the background concentration; or c) the source of contamination has been removed and if there had been a· release it would have reached the existing monitoring well network based upon the ground-water flow direction and rate, · 4. CTI may delete the analysis for turbidity once the Post Closure Plan has been modified and approved. 5. In the event that CTI has initiated a ground-water assessment at fue site it is no longer necessary to perform the statistical procedures. Once the Post Closure Plan has been modified and approved, CTI may discontinue the statistical procedure. 6-8. Once the Post Closure Plan, including the sampling and analysis section, has been modified and approved, CTI may implement the new procedures with the amendments noted below. a. The plan should specify that samples requiring a preservative (i.e. acid to samples for metals analysis, NaOH to samples for cyanide analyzes, etc.) should be checked in the field to determine if enough preservative has been added. This procedure should be implemented whether the preservative was added in the laboratory or in the field. b. The decontamination procedure for the hailers should be specified in the plan whether the procedure is implemented in the laboratory or in the field. c. The plan should specify fuat all water levels will be collected prior to initiating the well purging procedure at any well. d. The plan should specify the pmnp decontamination procedure. e. The plan discusses the use of a pump during the purging procedure. The plan also states that if a floating product layer is present then the pump will be lowered to the bottom of the well and purging will continue. This procedure raises the question of how CTI will be able to ensure that all of the liquid above the screened interval will be removed during the purging process. Mr. Glen Simpson May28, 1997 Page 3 of3 Once CTI has responded to the issues raised in items 1-3 above, a modification to the Post- Closure Plan may be resubmitted. Iftherc are any questions, please call me at (919) 733-2178, extension 218. ~!£~ Peter L.

LET Post·Closure Plan Modification Request Central Transport, Inc. Facility Charlotte, North Carolina Page 2 2) Reduce the, list of metal analytes from twenty-three to ten. CTI proposes to eliminate the following metals from sampling requirements: Aluminum, calcium, iron, magnesium, potassium, and sodium as there are no Practical Ouantitation Limits (POLs) listed in Appendix IX of 40 CFR Part 264 for these metals; Antimony, selenium, and thallium as these metals have never been detected in excess of their respective SW-846 method 6010 POLs in groundwater samples collected at the site; Arsenic as this metal has not been detected above National Drinking Water Standards or its SW-846 method POL at the site since June 1990; Beryllium as this metal has not been detected in excess of its SW-846 method 601 O POL in groundwater samples collected since the September 1991 sampling event; Cadmium as this metal has not been detected in excess of its SW-846 method 6010 POL in groundwater samples collected since the May 1991 sampling event; Copper and nickel as these metals have not been detected in the proposed Post-Closure monitoring wells in excess of their respective method SW-846 POLs since the June 1993 sampling event; See Attachment A for a summary of historical TAL metals analysis results. Information in Attachment A was obtained from Groundwater Monitoring Reports generated by O'Brien and Gere Engineers, Inc. and Rust Environment and Infrastructure. The following metals will be analyzed during the remainder of the post-closure period: Barium Lead Vanadium Chromium Manganese Zinc Cobalt Mercury Iron Silver Post-Closure Plan Modification Request Central Transport, Inc. Facility Charlotte, North Carolina Page 3 Analytical methods for these compounds are listed on page F-22 and F-23 of the revised Post-Closure Plan. Sampling and analysis for these ten metals will satisfy the monitoring requirements specified in 265.93(d)(3) and (4). 3) Eliminate cyanide as a required analyte. Cyanide has never been detected above its MCL during groundwater monitoring at the site. 4) Eliminate turbidity from the analysis requirements. 5) Eliminate statistical analysis to determine whether statistically significant amounts of contaminants have been released and impacted the groundwater at the site. Prior laboratory analytical results from groundwater sampling indicates contaminants have been released. 6) Revise the approved Sampling and Analysis Plan to allow use of Teflon bailers in lieu of a field decontaminated stainless steel bailer. 7) Revise the approved Sampling and Analysis Plan to state each Teflon bailer will be used at only one well and to eliminate field cleaning of sampling bailers. 8) Revise the approved Sampling and Analysis Plan to indicate that all preservatives are to be added to the sample bottles at the laboratory prior to arriving at the site. The above modification will necessitate revisions to the approved Post-Closure Plan. Attachment B contains the revised pages that are to. be inserted into the Plan upon approval of this modification request. Revised pages should be inserted into Section F of the Plan and the corresponding pages of the existing plan should be removed. In addition, a revised Sampling and Analysis Plan is included as Attachment C. This revised plan should replace Appendix E in the existing plan. All of the current Appendix E should be removed and replaced by the revised Sampling and Analysis Plan. Upon approval of this modification, CTI will submit a revised Post-Closure Cost Estimate to be included in the approved plan. Post-Closure Plan Modification Request Central Transport, Inc.

The asphalt and immediately underlying soil were removed from the stabilized sludge storage area during the decontamination of the storage area and were co-shipped to the Piedmont Landfill. Neither the contaminants contaminated concrete liner nor the asphalt were tested for prior to disposal. Both materials were assumed to be by contact with the sludge. By utilizing the same disposal facility, i.e. Piedmont Landfill, as that approved for disposal of the stabilized sludge and soil, the concrete liner and asphalt were properly disposed in accordance with the Closure Plan.

(WRS) has cornpleted the installation of the soil cover portion of the lagoon closure. Based on conductivity testing which was done on undisturbed samples taken from the clay cap, the measured hydraulic conductivity averaged approximately I 0- 6 cm/sec. WRS offers the following reasons why the clay cap conductivity was not the designed conductivity of I x JO-7 cm/sec I. The constructed conductivity differed from the laboratory predicted conductivity-Prior to the installation of the lagoon backfill. several locally available sources of clay were identified by WRS with the assistance of a Charlotte geotechnical engineering firm. This engineering firm which has considerable experience with landfill liner and cap construction, lent confidence to WRS that clay sources available in the Charlotte area would be suitable for the construction of the clay cap at the Central Transport facility. Landfill companies in the Charlotte area are successfully using locally available clay for clay liner construction. After several somces were inspected, the two best sources were submitted to a geotechnical laboratory. Results of the geotechnical testing on remolded samples, indicated that the design conductivity of Ix 10·7cm/sec was achievable with the clay from the Lake Norman Quarry. Based on this testing the Lake Norman Quarry was selected for the clay. Recommendations for the installed moisture and compaction parameters were also based on these tests. Throughout the course of installing the clay cap portion of the soil cover the recommended moisture and compaction conditions were maintained. Even though the recommended compaction effort was achieved, it appears that a slight difference has occurred between the laboratory predicted conductivity and the actual measured conductivity for the installed clay cap. A Westinghotise Electric Corporation ~ub$idi<ir-y I I I I I I I I I I I I I I I I I I Mr. Glen Simpson 17 November 1993 page 2 • • 2. A second clay sonrce was required-At end of the clay cap installation WRS had to obtain approximately 300 cubic yards of clay (less than 15% of total volume installed) from another source due to the original supply being depleted. Weather delays which occurred during the project resulted in the removal of a portion of the clay which was designated for WRS. The last 300 cubic yards needed to complete the clay cap was obtained from the Martin Marietta Beatties Ford Road Quarry. This alternative clay source was located after an exhaustive search within the greater Charlotte area. WRS was assisted by S&ME, Inc of Charlotte in finding this alternative clay source.

(WRS) was unable to provide the Certification letter for the lagoon closure project at the above referenced site. The delay associated with WRS issuing this Certification was due to two reasons: (I) The original Licensed Professional Engineer in the State of North Carolina who was assigned to monitor and certify the closure left WRS after the completion of the first phase of the project. The recently appointed P.E. required additional time to assemble and the review project data from the first phase. (2) The supply of clay which WRS located and tested for use in the installation of the clay cap was depleted. This resulted in WRS having to obtain approximately 225 cubic yards of clay from a different source. The resulting field density testing data obtained during the installation of this clay did not indicate that the required conductivity was reached. To resolve the question of conductivity described in item #2, WRS proposes that four additional undisturbed sample (Shelby Tubes) of the clay cap be obtained and tested to determine the vertical conductivity. We have contacted S&ME, Inc., the same company which performed the field density testing, to arrange this additional testing. S&:ME has given us a schedule for completion of the testing by the week of 27 September 1993. A Westinghouse Electric Corporation subsidiary, • • If these conductivity tests results are acceptable, WRS will provide the required Certification Letter for the project. We hope that the above described testing is acceptable to CTI. If you require any additional information, please contact us a your convenience.
