§ 194.21 Inspections

(a) The Administrator or the Administrator's authorized representative(s) shall, at any time:

(1) Be afforded unfettered and unannounced access to inspect any area of the WIPP, and any locations performing activities that provide information relevant to compliance application(s), to which the Department has rights of access. Such access shall be equivalent to access afforded Department employees upon presentation of credentials and other required documents.

(2) Be allowed to obtain samples, including split samples, and to monitor and measure aspects of the disposal system and the waste proposed for disposal in the disposal system.

(b) Records (including data and other information in any form) kept by the Department pertaining to the WIPP shall be made available to the Administrator or the Administrator's authorized representative upon request. If requested records are not immediately available, they shall be delivered within 30 calendar days of the request.

(c) The Department shall, upon request by the Administrator or the Administrator's authorized representative, provide permanent, private office space that is accessible to the disposal system. The office space shall be for the exclusive use of the Administrator or the Administrator's authorized representative(s).

(d) The Administrator or the Administrator's authorized representative(s) shall comply with applicable access control measures for security, radiological protection, and personal safety when conducting activities pursuant to this section.

40 CFR § 194.21 (U.S. EPA 1996) provides the U.S. Environmental Protection Agency (EPA) with the authority to inspect all activities at the Waste Isolation Pilot Plant (WIPP) and all activities located off-site that provide information relevant to any compliance applications.

The EPA conducted no inspection under the authority of section 194.21 prior to the 1998 Certification Decision. With the issuance of its 1998 Certification Decision (U.S. EPA 1998), the EPA identified inspections that may be performed under the authority at section 194.21. These include the following:

· The inspection of the panel closure system on waste panels that have been filled and are being sealed to confirm compliance with Condition 1 of the EPA's 1998 Certification Decision (U.S. EPA 1998)

· The verification that specific actions identified by the U.S. Department of Energy (DOE) in the Certification and supplementary information (and in any additional documentation submitted in accordance with Condition 4) are being taken to test and implement passive institutional controls

· Announced and unannounced inspections of activities at the WIPP and at all off-site facilities that provide information included in certification applications

· The inspection of the DOE's implementation of the monitoring plans that the DOE has set forth to demonstrate compliance with 40 CFR § 194.42

· The inspection of any records relevant to the Certification kept by the DOE, including those records required to be generated in accordance with the compliance criteria

· The inspections of approved quality assurance (QA) programs at the WIPP and at waste generator sites to ensure the programs are being adequately maintained and documented

After the 1998 Certification Decision, the EPA began using the authority given by section 194.21 to conduct inspections at the WIPP. Inspections include magnesium oxide (MgO) backfill, waste emplacement, the monitoring programs established to collect data for each of the monitored parameters identified in Table 21-1, and the examination of documentation (records) to verify compliance at the WIPP.

Table 21-1. Monitored Parameters

Monitored Parameters

Geomechanical Parameters

· Creep closure

· Extent of deformation

· Initiation of brittle deformation

· Displacement of deformation features

Hydrological Parameters

· Culebra groundwater composition

· Change in Culebra groundwater flow direction

Waste Activity Parameters

· Waste activity subsidence parameter

· Subsidence measurements

Drilling-Related Parameters

· Drilling rate

· The probability of encountering a Castile brine reservoir

The monitoring inspection activities included an examination of monitoring and sampling equipment both on- and off-site and underground. The EPA also reviewed sampling procedures and measurement techniques and verified implementation of an effective QA program for monitoring activities.

This provision of the EPA's Compliance Criteria was not applied prior to the 1998 Certification Decision. After 1998, the EPA used the authority given by section 194.21 to inspect the WIPP monitoring programs, MgO backfill, and waste emplacement requirements.

The 2004 Compliance Recertification Application (CRA-2004) (U.S. DOE 2004) did not address the EPA's inspection activities under section 194.21. However, the EPA inspection activities were addressed in Compliance Application Review Document (CARD) 21 (U.S. EPA 2006a). CARD 21 identified monitoring inspections and waste emplacement inspections that were conducted from March 23, 1999, through July 12, 2005. This information is duplicated in Table 21-2.

Waste Emplacement

The EPA had no findings or concerns during this inspection.

(U.S. EPA 2000b)

June 20-21, 2001

Monitoring

The EPA had one finding and no concerns. The finding noted that the subsidence monitoring program at the WIPP did not have an adequate written procedure to implement an effective QA program.

In response to the EPA's finding, the DOE developed a new subsidence procedure. The EPA evaluated the procedure and found it to be adequate.

(U.S. EPA 2001a)

June 21, 2001

Waste Emplacement

The EPA had no findings and one concern. The concern noted that the DOE did not appear to have a procedure that required proper documentation of off-normal events. This concern did not require a response from the DOE because the DOE provided all documentation requested.

(U.S. EPA 2001b)

June 26-28, 2002

Monitoring

The EPA had no findings or concerns during this inspection.

(U.S. EPA 2004a)

June 28 through July 1, 2004

Waste Emplacement

The EPA had no findings and one concern during this inspection. The EPA found that the DOE did not appear to have a real-time system to track and calculate the actual MgO placed with waste at disposal. This concern was resolved by using the WIPP Waste Information System (WWIS) to track the quantities of MgO.

(U.S. EPA 2004b)

July 12-15, 2005

Monitoring

The EPA had no findings or concerns during this inspection.

(U.S. EPA 2005a)

May 17-19, 2005

Waste Emplacement

The EPA had no findings and one concern during this inspection. The EPA found that the DOE needed to develop a formal procedure that guides the MgO emplacement decision-making process rather than using training materials, and that the WWIS needed to be back-populated with the quantity of emplaced MgO. In response to this concern, the WWIS was back-populated.

(U.S. EPA 2005b)

During each of the inspections listed in Table 21-3, the DOE provided the EPA with unfettered access to facilities, lists of records, access to these records as requested, and access to private office space. Additionally, the DOE actively supported the EPA's inspection activities. Based on the EPA's review and evaluation of the CRA-2004, the EPA determined that the DOE continued to comply with the requirements for section 194.21 (U.S. EPA 2006a).

Table 21-3 lists the seven inspections conducted by the EPA under the authority of section 194.21 since the inspections reported in CARD 21 (U.S. EPA 2006a).

During each of the inspections listed in Table 21-3, the DOE met all the requirements of section 194.21, providing the EPA with unfettered access to facilities, lists of records, access to the records requested, and access to private office space. Additionally, the DOE actively supported the EPA's inspection activities as required by section 194.21.

(U.S. EPA 2007c)

October 7, 2007

Unannounced inspection at the Advanced Mixed Waste Treatment Facility (AMWTF) and the Accelerated Retrieval Project at the Idaho National Laboratory (INL)

The EPA had no findings or concerns during the inspections. However, the EPA requested information on the process used for regrouping four pre-1970 buried waste streams. EPA also requested information for estimating transuranic (TRU), mixed TRU, and low-level waste volumes. On December 28, 2007, the DOE provided the EPA with the requested information. Letter from the EPA to the DOE (March 18, 2008) acknowledging receipt of additional information requested that adequately addressed the EPA concerns.

DOE document development and review process

The EPA made five process improvement recommendations.

(Reyes 2008)

The inspections section of the compliance criteria, 40 CFR 194.21, lists specific requirements related to the EPA's ability to perform inspections involving the WIPP. These requirements include unfettered and unannounced access equivalent to that of DOE employees, availability of records for review, and private office access if needed to perform inspections. The EPA evaluated the DOE implementation of these requirements at each of the inspections documented in Table 21-3, and found that the DOE actively supported EPA inspection activities.

Based on a review and evaluation of the CRA-2009 (U.S. DOE 2009) and supplemental information provided by the DOE (Federal Document Management System Docket ID No. EPA-HQ-OAR-2009-0330, Air Docket A-98-49), the EPA determined that the DOE continued to comply with the requirements of section 194.21 (U.S. EPA 2010b) since those reported in the CRA-2009.

Table 21-4 lists the inspections conducted by the EPA under the authority of section 194.21 since the ones reported in the CRA-2009.

During each of the inspections listed in Table 21-4, the DOE met all the requirements of section 194.21, providing the EPA with unfettered access to facilities, lists of records, access to the records requested, and access to private office space. Additionally, the DOE actively supported the EPA's inspection activities as required by section 194.21.
