Re: Post-TCRA Quarterly Inspection Report – April 2018

Introduction This memorandum describes the results of the April 2018 inspections of the armored cap cover, fencing, signage, buoys, and security cameras installed for the Time Critical Removal Action (TCRA) at the San Jacinto River Waste Pits Superfund Site (TCRA Site).

Background The TCRA was implemented by International Paper Company and McGinnes Industrial Maintenance Corporation (Respondents) under an Administrative Settlement Agreement and Order on Consent with the U.S. Environmental Protection Agency (USEPA) – Docket No. 06-12-10, effective May 17, 2010. A full description of the TCRA implementation is provided in the following associated project documentation:

• Removal Action Work Plan (Anchor QEA 2010, 2011) • Revised Draft Final Removal Action Completion Report (RACR; Anchor QEA 2012)1

The inspection described in this memorandum was conducted in accordance with the Operations, Monitoring, and Maintenance (OMM) Plan (Appendix N of the RACR; Anchor QEA 2012) and a subsequent USEPA-approved amendment to the OMM Plan.2 The OMM Plan specifies the timing, pertinent items, tolerances, and procedures for inspection, maintenance, and repair of the armored cap, fencing, and signage installed for the TCRA Site (Figure 1). David Keith, PhD, RG, CHG (Respondents’ Project Coordinator), received an email from Gary Miller of USEPA, dated

1 David Keith, Ph.D., R.G., C.H.G., Respondents’ Project Coordinator, received a RACR (in the form issued by USEPA) from Valmichael Leos via email on August 15, 2012; however, the appendices to the RACR, including the OMM Plan, were not provided to Dr. Keith as part of the document. The OMM Plan had been previously approved by USEPA (in an email from Mr. Leos dated January 18, 2012) and is assumed to remain unchanged. Respondents reserve all rights related to the changes made by USEPA to the Revised Draft Final RACR submitted by Respondents to USEPA on March 9, 2012. 2 The OMM Plan was attached to the Draft Final RACR, submitted to USEPA on November 22, 2011, and authorization to implement the OMM Plan was contained in an email from USEPA dated January 18, 2012. The OMM Plan was also attached as an appendix to the Revised Draft Final RACR submitted to USEPA on March 9, 2012. An addendum to the OMM Plan, dated February 29, 2016, was developed to describe the addition of security cameras, their monitoring, and notifications, and approved by USEPA on March 31, 2016.

May 8, 2018

February 16, 2016, directing Respondents to increase the frequency of cap inspections to quarterly until further notice.

Visual Inspection The visual inspection took place on April 5, 2018. The inspection included evaluation of the following TCRA elements:

• Inspection of the security fence and signage surrounding the TCRA Site • Inspection of the armored cap visible above the water line of the San Jacinto River • Visual confirmation that waste materials are not actively eroding into the San Jacinto River • Inspection of perimeter buoys and security camera system

The visual inspection was performed by Rick Coupe and Daleel Nangju of Anchor QEA. Photographs of conditions observed during visual inspections are provided in Appendix A. A summary of each facet of the visual inspection is provided in the following sections.

Armored Cap Photographs from the inspection of the armored cap are provided in Appendix A. The majority of the Eastern Cell armored cap was underwater at the time of the inspection on April 5, 2018. All the visible portions of the armored cap were observed to be intact, and no movement of cap materials was observed at any location during the visual inspection. For examples of the cap, see Photographs 1 through 6 in Appendix A.

Perimeter Fencing The perimeter fencing (Figure 2) on the west and east banks of the San Jacinto River was visually inspected for breaches or other indications of damage on April 5, 2018. No breaches or indications of fence damage were observed during the inspection. For examples of the site fencing, see Photographs 7 through 11 in Appendix A.

The portion of the fence installed along the south boundary of the San Jacinto River Fleet (SJRF) property was not included in the fencing inspection because the SJRF property is currently occupied by an active facility that conducts daily security checks as required by the U.S. Coast Guard and Transportation Security Administration for an active maritime fleeting area.

Signage “Danger” and “No Trespassing” signs are posted at regular intervals on the perimeter fencing surrounding the TCRA Site. All “Danger” and “No Trespassing” signs were observed to be in place

May 8, 2018

during the April 5, 2018, inspection. For an example of these signs, see Photographs 9 and 10 in Appendix A.

Three USEPA Public Notice signs are present around the TCRA Site in the following locations: 1) near the gate entry point for the perimeter fence north of I-10; 2) near a gate entry point south of I-10; and 3) at the end of the Texas Department of Transportation right-of-way north of I-10 near the San Jacinto River. For examples, see Photographs 13 and 14 in Appendix A. These three signs were observed to be in place and undamaged.

A total of 15 signs were installed around the perimeter of the land portion of the TCRA Site; the signs are mounted on steel posts and set in concrete pads. These signs are intended to face the San Jacinto River to deter water-based entry to the TCRA Site. For examples of these signs, see Photographs 12 and 15 through 17 in Appendix A. One sign was damaged by high winds and will be replaced. The Respondents are working with contractors to design and install a frame or stiffeners on the existing signs and posts to prevent similar damage by high winds in the future

Signage on the two vehicle access gates reminds entrants to “daisy chain” the lock properly prior to leaving the TCRA Site. These signs were observed to be in place and undamaged. For examples of these signs, see Photographs 11 and 18 in Appendix A.

The signs were in place and in good condition, with the exception discussed previously in this section. Table 1 summarizes the TCRA Site signage and tasks associated with their inspection as described in this section.

Perimeter Buoys Warning buoys were installed around the perimeter of the armored cap as outlined in the letter from Respondents’ Project Coordinator dated February 16, 2016 (Anchor QEA 2016a). The perimeter buoy system was visually inspected and found to be intact on April 5, 2018. See Photographs 6, 19, and 20 in Appendix A for examples.

Security Cameras Security cameras, installed as outlined in an addendum to the OMM Plan (Anchor QEA 2016b), were also inspected on April 5, 2018. The security camera system was operating normally during the inspection. For an example of the security camera apparatus at the TCRA Site, see Photographs 21 through 22 in Appendix A.

Survey The survey began on April 2, 2018 and was completed on April 17, 2018. The surveyor followed the track line spacing measurement intervals and accuracy requirements detailed in the OMM Plan (Anchor QEA 2012) for all survey work. Portions of the armored cap above the water surface or at a water depth too shallow to access by boat were surveyed using land-based topographic survey techniques.

Survey Tolerance Requirements The OMM Plan (Anchor QEA 2012) requires that each survey be compared with the prior completed survey using the following criteria:

1. Areas with elevations that are within 6 inches of the previous survey require no action. 2. Contiguous areas with elevation changes exceeding plus or minus 6 inches trigger a review of

the survey benchmarks for accuracy or movement. 3. Areas where surveyed elevations are 6 inches higher or lower than the prior survey for a

contiguous area larger than 30 feet by 30 feet require probing to measure the cap thickness.

Survey Results The survey data from the January 2018 and April 2018 inspection surveys were compared to evaluate the differences in the top of the armored cap elevation. These differences are shaded and shown on Figure 3. The survey results indicate continued deposition and periodic erosion of alluvial sediment on the surface of the cap.

The OMM Plan requires manual probing of armored cap thickness at areas identified by the topographic or bathymetric surveys as more than 6 inches lower in elevation than during the prior survey over contiguous areas of 30 feet by 30 feet. When the April 2018 survey was compared to the

May 8, 2018

January 2018 Quarterly Inspection, the results indicated that there was an irregular area of interest (AOI) where manual probing was required. USEPA was notified of the need for probing on April 19, 2018 and provided their approval for probing on April 20, 2018. The AOI shown on Figure 3 was probed on April 20, 2018, and the cap was found to be intact and to the required thickness. In response to a question from USEPA, the probing area elevations were compared to the elevations that were measured upon completion of the TCRA cap construction, and the current elevations in the probing area are essentially the same as those that were measured during the post-construction survey. Based on this comparison, the change between the January 2018 and April 2018 surveys represents movement of recently-deposited sediment on top of the cap. USEPA was notified of the probing and survey comparison results on April 25, 2018.

Inspection Summary The visual inspections conducted in April 2018 showed the security camera system was in place and operating normally; fencing and signage were intact, with one sign needing to be replaced; and the armored cap and perimeter buoy system remained intact with no visual deficiencies. The quarterly survey that was completed and compared to the January 2018 survey identified an AOI that required manual probing, and the probing indicated that the cap was the required thickness in the area.
