In accordance with the Solid Waste Statute, CRS 30-20-103 (2), a "technical evaluation" of the Application is required after the completeness review has been conducted, and the Division completed an initial technical evaluation The Division submits the following comments and questions Based on the applicant's responses, the Division may request additional information in order to clarify aspects of the Application before completing the technical evaluation. A formal recommendation of approval (or disapproval) of the Application per the Solid Waste Regulations will be made after the Division has completed its technical review. Technical Review Comments 1) Section 1 3, pg 2, paragraph beginning with "In accordance with ": The 2nd sentence a couple specific disposal sites, but not the site where the Facility is currently sending most waste (per site visit). Because the list of disposal facilities permitted to take various wastes and various levels of TENORM, it is suggested that the 1st sentence is sufficient, but the 2nd sentence can be eliminated 4300 Cherry Creek Drive 5 , Denver, Co 80246 1530 P 303 692-2000www colorado gov/cdphe I John W Hickenlooper, Governor I Karin McGowan, Interim Executive Director 2) Sections 1.3 and 1 4 general. It is stated that the facility will accept TENORM wastes with up to 50 pCi/g (above background) of radium 226/228 combined. There is no discussion of acceptance of TENORM wastes that may have uranium or thorium levels above 30 and 3 pCi/g (above background) respectively. Unless the EDOP and Risk Assessment are modified to accept higher levels of uranium or thorium, the EDOP should explicitly describe that wastes containing uranium and thorium above these levels will not be accepted Refer also to Comment 11. 3) Section 2 1 2, last sentence: This sentence refers to a process flow diagram as Figure 1 Should it say Figure 47 4) Section 4 0. This section describes a monitoring well system/layout that consists of groundwater monitoring wells MW -3 through -06 and an additional well to be located prior to construction of the Solids Processing Facility. Figures/Drawings 2 and 3 are referenced A Is MW -07, shown on these figures, installed? If so, please update this section accordingly B It is stated that groundwater flow direction is southeast towards monitoring wells MW -3 and -5 These wells would then be upgradient of the Solids Processing Facility The location of MW -07 might be downgradient of the westernmost part of the Solids Processing Facility Please provide a current potentiometric surface map of the groundwater based on data Please describe plans and locations for additional wells that can monitor downgradient of the central and eastern parts of the Facility and detention pond, or provide a basis for the lack of such monitoring C The last sentence of this section states that the Site Groundwater Monitoring Plan is included as Appendix E. Please correct to Appendix C, or as appropriate 5) Section 6 0 This section generally describes that all wastes, wastewater and washwater will be solidified and disposed at an appropriate disposal facility Also buildings, process areas, and concrete will be demolished and disposed. 6 CCR 1007-2, Part 1 (the Regulations) requires a cost estimate for a third party to complete these activities Please provide a defensible cost estimate as part of the EDOP After approval of the cost estimate, a mechanism for financial assurance must also be developed for approval Appendix C - Site Groundwater Monitoring Plan 6) Please update the initial 2 -page letter/plan, dated October 31, 2014, consistent with revisions to Section 4 0, per comment #4. 7) The last paragraph on the 1St page appears to have semi-annual and adjustment to quarterly reversed 4300 Cherry Creek Drive 5 , Denver, CO 80246 1530 P 303 692-2000 www colorado gov/cdphe John W Hickenlooper, Governor I Karin McGowan, Interim Executive Director 8) Please include, in Section 4.0 and/or in this appendix, an explicit requirement for submittal of monitoring reports to the CDPHE (and WCDHE if requested) 9) Please include boring and completion logs for each groundwater monitoring well 10) Attachment A. It is noted that this plan generally falls short of describing all requirements for groundwater monitoring as required by 6 CCR 1007-2, Part 1 However, because of the nature of materials managed at the facility and the fact that the Solids Processing Facility is not a disposal facility, it believed to be usable The analytes listed for water analysis should suffice for detection monitoring. The Division may unilaterally expand the list of analyses, should detection monitoring indicate impact to groundwater due to Facility operations. A The "Groundwater Trend Analysis" Section states that "Any BTEX constituents above the COGCC maximum allowable concentrations (MACs) discovered in a monitoring well water quality sample will be reanalyzed ". Please change this to read "Any BTEX constituent detection will be reanalyzed ". All references to COGCC MACs shall be replaced with 'detection' Appendix D — Radiological Dose Assessment 11) The radiological dose assessment report (the report) only evaluates the potential doses from 50 pCi/g of radium Since there is no dose assessment on uranium or thorium, the facility cannot be authorized to receive any waste with natural uranium above 30 pCi/g (above background; default background = 2 4 pCi/g) and natural thorium above 3 pCi/g (above background, default background = 1 3 pCi/g), in accordance with CDPHE TENORM interim policy and guidance dated February 2007 If the facility expects to receive wastes with uranium and thorium exceeding the above activity concentrations, the facility should provide risk assessments on the maximum uranium and thorium concentrations anticipated in the wastes to establish the appropriate acceptance criteria for uranium and thorium. 12) The report indicates that radium -226 normally dominates the naturally occurring radium, so that the report only evaluates the potential doses from 50 pCi/g radium -226, even though the proposed limit of 50 pCi/g is for radium -226 and radium -228 combined. It is our understanding that radium - 228 could have substantial concentrations in the oilfield wastes and radium - 228 would actually result in more doses than radium -226 with the same activity concentration Therefore, the report should evaluate the doses from 50 pCi/g of radium -228 as well. 13) The application indicates that NGL's customers in Weld County routinely produces wastes from oil and natural gas production The TENORM wastes from natural gas pipeline pigging operations could have elevated Pb- 210 and Po -210 (from radon) without elevated radium Since this report only 4300 Cherry Creek Drive S , Denver, Co 80246-1530 P 303-692-2000 www colorado gov/cdphe I John W Hickenlooper, Governor I Karin McGowan, Interim Executive Director evaluates doses from radium, the facility cannot be authorized to receive wastes from natural gas pipeline pigging operations until a risk assessment specific to the anticipated level of Pb-210 and Po -210 in these wastes is provided and approved. 14) Section 3.2: we understand that dose from radon in the MSPB is not expected to be high due to the use of ventilation. However, we would like to see some quantitative assessment on the dose in this section. Please provide the following information: air exchange rate in the room, expected air radon level, expected emission rate of radon at the ventilation point, some more ventilation information (such as how often it is run, etc.), the maximum amount of material at any one time that will be exposed in the room, and any other useful information 15) Please provide a detailed description on worker activities in MSPB and explain how Worker A, B, and C and Table 3 are representative of real worker activities. 16) What is the difference between Figure 1 and 3, and the difference between Figure 2 and 4? Why is the conveyor location in Figure 1 and 2 different from the location in other figures? Please provide a detailed description on what Figure 1 and 2 are presenting. The Department is authorized to bill for its review of technical submittals pursuant to Section 1.7 of the Regulations.
