NUMBER NM4890139088WIPP-ll-OIODear Messrs. Ziemianski and Sharif:The New Mexico Environment Department (Department) has received a Permit ModificationRequest to Update Ventilation Language, Add a Shielded Container, and Revise the WasteIsolation Pilot Plant (WIPP) Groundwater Detection Monitoring Program Plan, dated September29,2011, from the U.S. Department of Energy Carlsbad Field Office and Washington TRUSolutions LLC (the Permittees). The Permittees seek to modify the Hazardous Waste FacilityPermit for the WIPP and request that the Department process the request as a Class 2 permitmodification under the regulations at 40 CFR § 270.42(b). For the reasons explained below, Iapprove with changes two items of the modification request and deny one item.All items in the permit modification request were subject to a sixty (60) day public commentperiod, which ran from October 5, 2011 through December 5,2011. The Department receivedwritten comments on the request from eighty individuals and organizations. A large majority(77) of public comments addressed item 2, the request to add provisions to the permit forshielded containers for remotely-handled radioactive waste. The Department received only afew minor public comments regarding item 1, the request to modify the ventilation requirements

Messrs. Ziemianski and SharifJanuary 31, 2012Page 2at the facility, and item 3, the request to modify the facility groundwater monitoring plan. TheDepartment approves these modifications in accordance with 20.4.1.900 NMAC (incorporating40 CFR § 270.42(b)). The Department has made some changes to the permit modificationrequest. Changes include revision ofthe ventilation language so that the requirement forventilation in an active remote handled waste room with workers present is not removed. Thisrevision to the proposed language is made several section of the permit so that the requirement isconsistent throughout the permit.Under 20.4.1.900 NMAC (incorporating 40 CFR § 270.42(b )(7)), the Department may deny aClass 2 permit modification request if the modification request is incomplete; it does not complywith applicable requirements; or it fails to protect human health and the environment. During itstechnical review of the modification request for shielded containers, the Department noted thatnumerous sections in Part 3, Attachment AI, A2, Cl, D, E and G must be revised to conform tothe permit modification. In addition, 40 CFR 270.42(b), Appendix I, item F.3.a states changes ofstorage of different wastes in containers that do not require additional or different managementpractices from those authorized in the permit are Class 2 changes. The use of shielded containersdoes not fit this category as the facility will not be using different waste but will be usingdifferent containers.Numerous public commenters identified similar issues with the modification request.Furthermore, the Department does not have sufficient information to correct the technicalinadequacies in the application and approve the modifications "with changes" under 20.4.1.900(incorporating 40 CFR § 270.42(b)(6)(i)(A)). Consequently, the Department is denying thepermit modification request to add provisions for shielded containers.Enclosed are the revised pages of the modified permit in redline-strikeout to help the readerrapidly identify each modification. Also enclosed is an electronic version of the modifiedpermit, dated January 31, 2012. An electronic version of the modified permit has been postedfor the public on the Department's WIPP Information Page athttp://www.nmenv.state.Dm.us/wipp/download.htmlThe enclosed revised permit also includes the two Class 1 permit modifications submitted sinceNovember 2011. A separate letter sent January 18,2012 addressed the specifics of thosechanges.The permit modification shall become effective thirty days after notice of the decision has beenserved on the Permittees pursuant to 20.4.1. 90 1.A(1 0) NMAC. Thus, the effective date is March1,2012.The Department will provide full response to all public comments under separate cover.

The underground system Is11 designed to provJje control 01 potential airborne contaminants in the event of an accidental12 release or an undergrolJ'ld lire.j, The main underground ventilation system is dMded into four separate flows (Figure A2·9): oneI. flow serving the mining areas, one S8f\ling the northern experimental areas, one 58f\1Wlg the15 disposal areas, and one S8N1ng Ihe Waste Shaft and station area.

The six fans, connected by the ctJctwork to the lKKlerground exhaust shaft22 so thai they can ndependently draw air through the Exhaust Shaft, are divided Into two groups.23 One group consists ollhree main exhaust fans, two of which are utilized to provk:le the nominal~ 4 air flow of 425,000 standard It' per min (SCFM) throughout the WIPP lacllity underground during25 normal operation. One main fan may be operated in the alternate mode to provJje 260,00021!1 SCFM underground ventilation flow. These fans are located neSI the Exhaust Shaft. The27 second group conslsls of the remaining three filtration fans, and each can provIde 60,000 SCFM28 of air flow. These fans, located at the Exhaust Filter Building, are capable of being employed211 during the IIItr8110n mode, where exhaust is diverted through HEPA !HIers, or In the reduced or30 mInimum vent1ialion mode where air is not drawn through the HEPA filters. In order to ensure31 the miscellaneous unit environmental performance standards are met, a minimum running32 annual average eKhausl rale 01260,000 SCFM will be maintained.33 The undefgfoond mine ventilation Is designed to supply sufficient quanlitJes of air to all areas 01,.. the repositoty.

Inspections of the Cask Unloading Room, Hot Cell, Transfer Cell, Facility Cask8 Loading Room, RH Bay and radiation monitoring equipment will be recorded on data sheets. In9 addition to the inspections listed in Tables E-1 and E-1a, many pieces of equipment are subject10 to regular preventive maintenance. This includes more in-depth inspections of mechanical11 systems, load testing of lifting systems, calibration of measurement equipment and other actions12 as recommended by the equipment manufacturer or as required by DOE Orders. These13 preventive maintenance activities along with the inspections in Tables E-1 and E-1a make14 mechanical failure of waste handling equipment unlikely. The WIPP Safety Analysis Report15 (DOE, 1999) and the WIPP Remote-Handled Waste Preliminary Safety Analysis Report (RH,.

Drill-stem tests conducted in the Castile during construction of the WIPP facility ~30 determined its permeability to be lOwer than detection limits; however, the hydraulic conductivity31 has been conservatively estimated to be less than 10" tI (3 x 10·g m) per day.

The substantial barrier will be constructed from available non·tlammable22 materials such as mined salt (Figure NH).23 The bulkheads (Figure Nl-2) serves to block ventilation at the intake and exhaust of the filled24 panel and prevent personnel access. The bulkhead is constructed as a typical WIPP bulkhead25 with no access doors or panels, The bulkhead will consist of a steel member frame covered with26 galvanized sheet metal, and will not allow personnel access. Rubbor G()fl¥9.YOF beltFlexible27 fla shing will be used as a gasket to attach the steel frame to the salt, thereby providing an28 effective yet flexible blockage to ventilation air. Over time, it is possible that the bulkhead may29 be damaged by creep closure around it. If the damage is such as to indicate a possible loss of30 functionality, then the bulkhead will be repaired or an additional bulkhead will be constructed31 outside of the original one.32 The existing voe monitoring lines as specified in Attachment N, Section N·3a(2), ~ Sampling33 Locations for Disposal Room voe Monitoring", will be used for sample collection in each34 disposal room for Panels 3 and 4. The sample Jines and their construction are shown in Figure35 N1·3. In addition to the existing voe monitoring lines, five more sampling locations will be used36 to monitor for hydrogen and methane. These additional locations include:37 • the intake of room 1PERMIT ATIACHMENT NtPage NH of 11

This will maximize the sampling efficiency for7 these lighter compounds.8 N1-3 Samplinq Frequency9 Sampling frequency will vary depending upon the levels of hydrogen and methane that are10 detected.11 • If monitored concentrations are at or below Action Level 1 as specified in Pennit Part12 4, Tabte 4.6.5.3, monitoring will be conducted monthly.13 • If monitored concentrations exceed Action Levell as specified in Permit Part 4, Table14 4.6.5.3, monitoring will be conducted weekly in the affected filled panel.15 N1-4 Sampling16 Samples for hydrogen and methane will be collected using subatmospheric pressure grab17 sampling as described in Environmental Protection Agency (EPA) Compendium Method TO-15" (EPA, 1999). The TO-15 sampling method uses passivated stainless-steel sample canisters to19 coliect integrated air samples at each sample location. Flow rates and sampling duration may20 be modified as necessary to meet data quality objectives.21 Sample lines shall be purged prior to sample collection.22 Nl-5 Sampling Equipment23 N1-5a SUMMA s Canisters24 Stainless-steel canisters with passivated or equivalent interior surlaces will be used to collect25 and store gas samples for hydrogen and methane analyses collected as part of the monitoring26 processes. These canisters will be cleaned and certified prior to their use in a manner similar to27 that described by Compendium Method TO-15 (EPA, 1999). The vacuum of cert~ied clean28 canisters will be verified upon initiation of a sample cycle. Sampling will be conducted using29 subatmospheric pressure grab sampling techniques as described in TO-15."" N1-5b Sample Tubing31 Treated stainless steel tubing shall be used as a sample path and treatment shall prevent the32 inner walls from absorbing contaminants.33 Any loss of the ability to purge a sample line will be evaluated.

Waste 150lall0l1 Pilot PlantHazardous Waste PermitJaouary 3 1. 20120-2 Objective2 The objective of this plan is to describe how the ventilation requirements in the Permit will be3 met. This plan achieves this objective and documents the process by which the Permittees4 demonstrate compliance with the ventilation requirements by:5 • Maintaining an annual running average of 260,000 scfm through the underground5 repository7 • Maintaining a minimum of 35,000 scfm of air through the active disposal-rooms where8 waste disQOsal is taking place and when workers are present in the rooms9 This plan contains the following elements: Objective; Design and Procedures; Equipment10 Calibration and Maintenance; Reporting and Record Keeping; Quality Assurance.11 0-3 Design and Procedures12 This section describes the four basic processes that make up the mine ventilation rate13 monitoring plan:14 • T~st and Balance, a periodic re-verification of the satisfactory performance of the entire15 underground ventilation system and associated components15 • Monitoring and calculation of the Running Annual Average of the Total Mine Airflow to17 verify achievement of the 260,000 scfm minimum requirement18 • Monitoring of active gisfK)63~ room(s) to ensure a minimum flow of 35,000 scfm19 whenever waste d!sposalls taking place and workers are present in the room20 • Quarterly verification of the total mine airflow21 0-3a Test and Balance22 0-3a(1) Test and Balance Process23 The WIPP ventilation system and the underground ventilation modes of operation are described24 in Perm~ Application A2-2a(3). The Permi"ees shall verify underground ventilation system25 performance by conducting a periodic Test and Balance. The Test and Balance is a26 comprehensive series of measurements and adjustments designed to ensure that the system is27 operating within acceptable design parameters. The Test and Balance is an appropriate method28 of verifying system flow because it provides consistent results based on good engineering29 practices. The testing of underground ventilation systems is described in McPherson, 1993.30 Once completed, the Test and Balance data become the baseline for underground ventilation31 system operation until the next Test and Balance is performed.32 The ''Tesf portion of the process shall involVe measuring the pressure drop and air quantity of33 every underground entry excluding alcoves or other dead end drifts. In addition, the tests shall34 verify resistance curves for each of the main regulators, measure shaft resistance, and measure35 main fan pressure and quantity. This is done at the highest achievable airflow to facilitatePERMIT ATIACHMENT 0Page 0-3 01 ~H

From these measurements the frictional resistance of the system is2 determined.3 Pressure shall be measured using the gage and tube method, which measures the pressure4 drop between two points using a calibrated pressure recording device and pitot tubes. Pressure5 drops across the shafts shall be measured by either calibrated barometers at the top and6 bottom of shafts or the gage and tube method. Airllow shall be measured using a calibrated7 vane anemometer to take a full entry traverse between system junctions. Fan pressure shall be8 measured using a calibrated pressure recording device and pitot tube to determine both static9 and velocity pressure components.10 Multiple measurements shall be taken at each field location to ensure accurate results." Consecutive field values must fall within ±5% to be acceptable. These data shall be verified12 during the testing process by checking that:13 • the sum of airllows entering and leaving a junction is equal to zero; and.14 • the sum of pressure drops around any closed loop is equal to zero.15 Once the measurements are taken, data shall be used to calculate the resistance of every16 underground drift, as well as shafts and regulators using Atkinson's Square Law17 P=R x Q218 where the pressure drop of an entry (P) is equal to a resistance (R) times the square of the19 quantity of air flowing (0) through the circuit.20 The "Balance" portion of the process shall involve adjusting the settings of the system fans and21 regulators to achieve the desired airllow distribution in all parts of the facility for each mode of22 operation. Particular emphasis shall be given to the active disposal room(s) in the Waste23 Disposal Circuit to ensure that a minimum airllow of 35,000 scfm is achieved. The system24 baseline settings for the current Balance shall be established from the previous Test and25 Balance. Adjustments shall then be made to account for changes in system resistance due to26 excavation convergence due to salt creep, approved system modifications, or operational27 changes.28 The Permittees shall use a commercially available ventilation simulator to process Test and29 Balance field data. The simulator uses the Hardy-Cross Iteration Method (McPherson, 1993) to30 reduce field data into a balanced ventilation network, including the appropriate regulator settings31 necessary to achieve proper airflow distribution for the various operating modes. Once32 balanced, the same simulator shall be used to evaluate changes such as future repository33 development and potential system modification before they are implemented .34 The Test and Balance process culminates in a final report which is retained on site. Following35 receipt of the Test and Balance Report, the Permittees shall revise the WIPP surlace and36 underground ventilation system procedures to incorporate any required changes to the37 ventilation system configuration. The Test and Balance data shall be used to adjust the38 operating range of fan controls. waste tower pressure, auxiliary air intake tunnel regulator39 settings, underground regulator settings, and door configurations. The model data and40 procedure changes shall be used to establish normal configuration settings to achieve the41 desired airllow in the underground. These settings shall then be modified by operationsPERMIT ATTACHMENT 0Page 0-4 of ~ '4

This ensures that3 the facility is operated at the design airflow rate for each ventilation mode.• 0-3a(2) Test and Balance Schedule5 The Test and Balance is generally conducted on a 12- to 18-month Interval, but in no case shall6 the interval between consecutive Test and Balance performances exceed 1 B months. This7 interval is sufficient to account for changes in the mine configuration since over this period the8 ventilated volume changes very little. The quality and maintenance of ventilation control9 structures (e.g., bulkheads) is excellent, so leakage is small and relatively constant. Historic test10 and balance results confirm that changes between test and balances fall within anticipated11 values.12 0-3b Running Annual Average of the Total Mine Airflowf3 0-3b(1) Monitoring Total Mine Airflow14 The Permittees shall use the Central Monitoring Room Operator's (CMRO) Log to monitor total15 mine airflow. Run-times for the various modes of operation shall be entered into the CMRO Log.16 For example, if the CMRO Log indicates that the ventilation system was configured for Alternate17 Mode (one main fan) at 8:00 am, and that this configuration was maintained until 11 :30 am, a18 total of 3.5 hours of run-time in Alternate Mode would be recorded. Run tImes are recorded to19 the nearest quarter hour. The CMRO shall record each time when the ventilation system20 configuration is changed, including periods when there is no ventilation.2f 0-3b(2) Calculation of the Running Annual Average of Total Mine Airflow22 The Permittees shall calculate the running average flow rate on a monthly basis. The Permittees23 shall use the logged runtime data for various modes of operation (as described in 0-3b(I)) and24 the nominal design flow-rates for the various modes presented in Table 0-1 to calculate the25 average monthly flow rate for the facility.26 The average monthly mine flow rate is computed monthly using the following formula:27 Monthly Average Flow Rate = ((Nonnal Mode Run-time (hrs.) x 425,000 scfm)28 + [Alternate Mode Run-time (hrs.) x 260,000 scfm)29 + [Maintenance Bypass Run-time (hrs.) x 260,000 selm)30 + [Reduced Mode Run-time (hrs.) x 120,000 scfm)3f+ [Minimum Mode Run Time (hrs.) x 60,000 scfm)32 + [Filtration Mode Run-time (hrs.) x 60,000 selm))33 I 730 Hours per month.34 The running annual average of total mine airflow annual average flow rate shall be calculated35 using the monthly averages and the following formula:36 Annual Average Flow Rate = L Monthly Average for Previous 12 Monthsgt238 The use of an average value of 730 hours per month in the monthly average calculation is39 reasonable, given that all the numbers involved are very large and that the final use of thePERMIT ATTACHMENT 0Page 0-5 01 ~ 14
