1 NOC History

2 In July 2006 the twelve (12) passively vented caissons iri the 218-W-4B biirial groilitd were closc:4 as 3 legacy sources for the Air Operating Permit (AOP), FF-01 license. In 2012, it was recognized that these 4 vents were not included in the FF-0 I Table 2-1, and efforts were initiated between WDOH _and DOE/RL 5 to iricmporate the vents irito the FF-01 license. It was decided that inclusion of the vents into the FF-01 6 Table 2.1 as insignificant ~ssion uniJs was not appropriate and the caisson vents should be licensed 7 individually.. This NOCA provides for the inclusion of the caisson vents into the FF-0 I license.

24 5 Process Description

25 Regulat_orj! Requireme_n_t: Describe t/Je chemical and physical processes upstream of th_e em_ission unit(s). 26 WAC 246-247;1 JO Appendix A(5).

27 Underground caissons contajn. small closed packages (I to IO gallon 'paint cans') of remote handled (RH) 28 mixed fission product (MFP) and transuranic (TRU) wastes with high levels of radiation. A small 29 . percentage of the package lids became unsealed whei;i th!' pai;kages were dropped d_own tlJ.!l caisspn chirte. 30 The caissons are reinforcedcCOncrete cylinders buried approximately 4 meters below grade. The caissons 31 have 0.9 meter diameter inlet chutes that have been offset tci ellimnate direct radiation shine from the 32 stored wastes and equipped with an inlet chute cap to seal off the secondary pathway for fugitive 33 emissions. The 218-W-4B burial trench contains twelve (12) caissons. Four (4) of the caissons contain 34 alpha contaminated waste and are designated Alp_ha-1 through Alpha-4. Six (6) caissons contajn 35 beta/gamma contaminated waste and are designated MFP-1 through MFP-6. One (I) caisson contains 36 mixed waste products and is designated as UNI-I .. This caisson became plugged in 1978 and has a 37 concrete shield box over the inlet chute. The final caisson was never used and is d!lsignated Alpha-5. The 38 caissons are passively vented through high-efficiency particulate air (HEP A) filters. During filter aerosol

5 The radionuclides of concern exist in liquid and particulate sol_id forms. For purposes of ~stimating 6 potential and actual emissions and resultant impacts to the maximally exposed individual (MEI), each 7 radionuclide contained in a caisson is represented as curies (Ci). Where a total beta/gamma radionuclide 8 is identified it is assumed to be Sr-90 and is represented in this application as cmies (Ci). These 9 assumptions provide a conservative PTE for emissions from each passive caisson vent. Radionuclides of

17 9 Effluent Monitoring System

18 Regulatory Requirement: Describe the effluent monitoring system for the proposed control system. 19 Describe each piE!ce of monitoring equ_ipment and its rrion_itoring capability, including detection limits, for 20 each radionuclide that could contribute greater than ten percent of the PTE TEDE to the MEI, or greater 21 than 0.1 mremlyr PTE 'FEDE to the MEi. dr greater than twenty-five percent of the TEDE to th_e MEI. 22 after controls. Describe the method for monitoring or calculating those radionuclide emissions. Describe 23 the.method with detailsufficient to demonstrate compliance with the applicable requirements. WAC 246-24 247-1 JO Appendix A(9).

25 The potential unabated offsite dose associated with caissons MFP-2 and UNI-I for normal operation is 26 calcuiattid t_o be Jess than 0.1 Illlllirem per yc:ar (mrem/yr). Therefore, in accordance with 40 CFR 61, 27 "National Emission Standards for Hu.ardous Air Pollutants," Subpart H, '-'National Emission Standards 28 for Emissions ofRadionuclides Other Than Radori from Department of Energy Facilities," periodic 29 confirmatory measurements (PCM) will be made to verify the low emissions using the proposed alternate 30 monitoring method described below. The existing.200 Area network system for near-facility monitoring 31 (DOE/IU,-91-50, Envi,ronmentl11 Monitoring Pla_n Un_ited Sta_tes Depa_rtmi!_n_t of En_e_rgy Richfand 32 Operations Office) will continue to be used to verify low emissions during MFP-2 and UNI-I operations. 33 This is the accepted primary method for monitoring any diffuse or fugitive emissions generated by the 34 continued storage of radionuclide wastes in the 218-W-4B caissons, The near facility monitoring network 35 data for- stations N433, N457, N555, and N964 will be trended on an annual basis to verify continued low 36 enlissions ~m tile cai_s_sons.

37 The potential unabated offsite dose associated with caissons MFP-1, MFP-3, MFP-4, MFP-5, MFP-6, 38 Alpha-I, Alpha-2, Alpha-3 and Alpha-4 for nollllll_l operation is c_alculat~ to be greater than 0.1 millirem 39 per year (mrem/yr) and requires continuous monitoring. Due to the passive nature of the vents, it is 40 impractical to measure the effluent rates in the manner required by 40 CFR 61.93. The low effiuerit flow 41 rates (0.25 ft/sec) would re,quire approximately a 170 day sample period using an extractive isokinetic 42 sampling system to collect enough sample volume (20,000 ft3) to meet the method 114 quality 43 requirements. The effluent flow rate can be expected to vary somewhat due to the diurnal heating and

5

02/10/15



I cooling exerted on the caisson ventstack and the associated 'stack effect'. An average effluent flow rate 2 of 0.25 ft/sec is proposed as the alternative to a measured flow rate required by 40CFR61.93(b )(3) and is 3 derived from similar passively ventil;lted stacks at the Hanford site. Historic radiological contamination 4 survey data upstream of the HEP A filter inlet is consistently less than detectable for removable alpha and 5 beta/giim.tria contamination. The less than detectable value is defined as no instrument deflection when 6 scanning a Large Area Wipe at I inch per second for alpha and 2inches per second for beta/gamma at 1/8 7 inch from the surface ofthe wipe.

8 An alternate monitoring method is proposed for the continuous and PCM monitoring requirements. 9 Annually, a smear will be taken upstream of the HEP A filter. If detectable contamination is discovered, a

19 smear w,iI h:e taken downstream of the HEPA filter. If conta:mination above 20 dpm/i 00cm2 alpha or 11 1000 dpm/100cm2 beta/gamma is·found downstream of the HEPA filter, the source of the downstream 12. contamination will be investigated and corrected. This alternate monitoring method does not 13 underestimate emissions as tJ:ie clata is collected upstrellln of the abaten).ent dc:Mce for non-detectcable 14 contamination and immediately downstream of the abatement device in the event contamination is 15 discovered upstream of the abatement device. liJ. addition, the riear facility monitoring network data for I_ 6 stat_ions N433, N457, N555 and N964 will be trended on an annual basis to verify continued low 17 emissions from the caissons. The potential for the acute release of the entire caisson inventory is 18 extremely lciw due to the location below ground level, the low verit velocity and reduced (i;e minimal) 19 motive forces within the qaissons. If a release were to occur, it would be of a chronic low volume nature, 20 The use of the alternate monitoring protocol is appropriate for this type ofreleasescenario. The near 21 facility monitoring program meets the method 114 requirements and is well suited to detect this type of 22 release.

23 10 Annual Possession Quantity

24 Regulatory Requirement: Indicate the annual possession quantity (APQ) for each radionuclide. 25 WAC 246-247-1 JO Appendix A(JO).

26 On an annual basis, Table I details the radionuclides and associated APQ for each caisson being 27 registered. The APQ value is provided as a matter of information as the 12 September 2003 Settlement 28 Agreement (Docket Number 03-03-C-2000R1') estaJ>lished that Depa$1e1,1t of Energy, Richland 29 Operations facilities may not have radionuclide quantity limitations placed upon them through a licensing 30 agreement.

31 11 Physical Form of Each Radicmuclide

32 Regulatory Requirement: Indicate the physical form of each radionuclide in inventory: solid, particulate 33 solids, liquid, or gas. WAC 246-247-110 Appendix A(JJ).

34 The radionuclides in inventory are present as particulate solids at ambient conditions. Caisson MFPal 35 also con1ains one radionuclide present.in liquid form.

5 The radionuclides Cr-51, Mn-54, Fe-59, Co-60, Src90, Zr-90, Ru-106, Sb-125, Cs-134, Cs-137, Ce-144, 6 Pm-147, Eu-154, Po-210, Th,232,U-233, U-235, U-238, Np-237, Pu-238, Pu-239, Am-241,and all 7 associated daughter products are released as partjculate solids. The rallionucJjdetritium (H-3) is released 8 as a liquid particulate.

9 13 Release Rates

10 R_eguJatory Requireme,it: Release rates:

11 New emission uriit(s): Give predicted release rates withou/any e171issions control equipment (the PTE) 12 a11d with _the proposed control equipment using the efficiencies described in subsection six '(6) of this 13 section.

14 Modified (!mission unit(s): Give predicted release rates without any emissions control equipment (the 15 PTE) and with the existing and proposed control equipment using the efficiencies described in subsection 16 six (6) of this section. Provide tiie latest }'(!ar 's emissio11s data or emissions estimates.

17 In all cases, indicate whether the emission unit is operating in a batch or continuous mode. 18 WAC 246-247-110 Appendix A(J3).

19 The PTE is defined in WAC 246°247-030(21) as the rate of release ofradioriuclides from a:n emission 20 unit based on the actual or potential discharge of the effiuent stream tl_µit woulci result if all .abatement 21 control equipment did not exist, but operations are otherwise normal. The PTE is determined by 22 multiplying the APQ, discussed in Section 10, and applying the release factors defined in WAC 246-247-23 030(21)(a) for liquid and si:>lid particulates (Table I). An estimate of the unabated and abated dose in 24 l_ll!el]l/yr to an MEI is determined by applying the dose-per-unit release factors as published in DOE/RL-25 2006°29, CalculatingPotential-to-Emit Radiological Releases and Doses. Do:se-per--unit relc:_1,stifactors 26 are presented for both tl:ie OJ).-siJ.e and off-site individual, with consideration given for the release point 27 (i.e.; less than a 40-meter stack height) inTable 2. The emission unit.is passively vented on a continuous 28 basis.

29 14 Location of Maximally Exposed Individual

30, Regulatory Requiren,p,t_: Ide_n_ti.fy the MEI by d_is_ta_n,ce and direction from the emission unit(s). The MEI 31 is determined by considering distance, windrose data, presence of vegetable gardens, and meat or milk 32 producing animals at unrestricted areas surrounding the emissioTJ, ynJ! .. WAC 2 46-24 7-11 0 Appendix 33 ,:1(14).

34 The onsite MEI relative to emissions from the cais~ons is located a~ the L;iser In~erometer Gravit)ltional 35 Wave Observatory (UGO), approximately 18.3 kilometers east southeast of the Reduction Oxidation 36 Facility (S Plant), conservatively chosen to represent.200 West Area. The offsite MEI resides near the 37 Hanford Site, approximately 22 kilometers southeast ofS Plant.

7 D<>se ll!ltima~!l.S for unit cllf(e (Ci) rel~ses of selected radionuclides were calculated for emissions from 8 the 200 West Area. These dose estimates were calculated for an onsite member-of the public working at 9 LIGO; who works within the Hanforil Sitebouridilry, and who e:ats food gro\YIJ. regio1:µil)y

10 (DOefR!,-2006-2_9). Simil/lfly, dose estimates were calculated for an offsite member of the public 11 residing near the Hanford Site (approximately 22 kilometers to the southeast ofS Plant), and coilsuriifug 12 food produced entirely.at the residence location (DOE/RL-2006-19).

13 Using the unit dose factors, and the release rates from Section 13, estimated potential abated and iinabated 14 TEDEs to the offsite and onsite MEis are sho\Vll in Table 2. Unabate<i elllissions iJI curi!l_s were 15 detei:miJ)ed by applying re.lease factor 1.0E-03 for liquids and particulate solids directly to the.APQ 16 inventory values.

10 16 BARCT/ALARACT Assessment(or Cost Factors of Control Technology)

11 Regulatory Requirement: Provide cost factors for cdnstru.ctioT}, operaJ(dn, anti 1}J!!in_tentJ.nc_e of /he 12 proposed control tec!Jnology components and system, if a BARCTor as low as reasonably achievable 13 control technology (ALARACT) demonstration is not submitted with the NOC. WAC 246-247-1 JO · 14 AppendixA(16).

15 The control technology for existing emission units is ALARACT consisting of HEP A filtration of the 16 passively ventillited caissons, WAC 246~247--030(6) states that control t~hnology that meets BAR.CT 17 requirements also m~s ALj\RACT requirements. Pursuant to WAC 246-247°110, Appendix A, Item 18 # 16, cost factors for construction, operation, and maintenance of proposed tecliriology requirements are 19 not required, as the Washington State Department of Health has provided wdance .in a I~ to DOE, 20 that HEP A filters are general.ly considered BAR CT for particulate emissions (Conklin 1992). Because 21 the key radionuclides of concern are particulates, it is proposed that the control tecliriology described in 22 Section 6.0 be accepted as ALARACT. Compl1ance with thi: substanµve ALARACT technology 23 staµ.dards is described in Section 18.

24 17 Lifetime ofthe Faci(Jty Process

25 Regulatory Requirement: Provide an estimote of the lifetime for· the facility process with the emission 26 rates provided in this application. WAC 246-24i-J io Appendix A(ii).

FOR THE 218'-W-4B CAISSONS

I The ASME/ANS.I codes provided are applicable to forced ventilation systems and HEPA filters. The 2 caissons are passively ventilated. The 4.0 CFR 61 Appendix A standards govern the testing of forced 3 ventilation systems and are not applicable to a passively ventilated .system. The ASME AG0 I code 4 sections for ventilation design and sampling systems is designed for forced ventilation s~ems aIJd are 5 not directly applicable to passively ventilated systems. The HEPA filter system is designed to meet the 6 ASME AG-I and ASMJ;: N509 stllndlµ-ds. Th.e ANSI NB.I st_andards allow for a graded approach for 7 effluent monitoring systems and focuses on forced ventilation systems. The pas·sive ventilation system cif 8 the caissons does not allow for timely extractive sampling of the effluent due to the low effluent flow 9 volumes. WAC 246-247-075 requires that the quality assurance program be compatible with ASME

IO NQA-1. Quality assurance for the Near Facility Monitoring sample collection and analyses will be 11 implemented in accordance with the NESHAP Method 114 requirements.

12 The HEP A filters are in-place leak tested annually or upon replacement in accordance with a written 13 procedure that addresses testing and visilal inspections based on ASME N510 and ASME N5l I, and shail 14 have a minimllDl ~ffici.ency of99.95% as.required by DOE Handbook DOE-HDBK-1169-2003 at normal 15 operating flow rate. In addition, filters will be aerosol tested when replacement filters are manufactured. 16 The mariufacturettests the filters to verify it meets the 99.97% aerosol test performance criteria.

This notific~tion is provided to the State of Washjngton, Department cifEcology (Ecology), the Washington S~te DepartmentcifHealth (WDOH); and the U.S. Environmental Protection Agency (EPA) as nc,tice of an off-pemnt change, described as follows.

The following changes are allowed pursuant to WAC 173-401 -724( I), WAC 173-401-724(2), aJ!d WAC 173-401-724(6): I. Change.is not specifically addre_ssed or prohibited by the.AOP tenns and conditions; 2. Change does not weaken the enforceability of the existing AOP conditions; 3. Changeis not a Title I modification or subject to the acid rain requirements under Title IV ofthe'FCAA; 4. Change meets all !ll'Pii~le requirements and does not violate an existing pennit temi or condition; 5. Change has complied with applicable preconstruction review requirements es~blished pursuant to

RCW 70.94.152.

Descrintion.oftbe cbau:2e: . . .

In Jilly 2006, the twelve (12) passively ven.ted caissons in tlie2l8-W-4B burial trench were closed as legacy sources for the Air Operating Permit (AOP), FF-0 I license. Recently it has been recognized th!l,t these vents are not included in the FF-01 Table 2-1, and that inclusion of the vents into the FF-01 Table.2.1 as insignificant emission u11_its is not appropriate and the caisson vent§ should be licensed individually.

The proposed acti<>n for this Notice of Construction Application (NOCA) is to individually register eleven (11) of the twelve (12) caisson vents as p;JSsive major or minor point sources (WAC 246-247-060(2)). Caisson Alpha-5 does not require registration as it has never been used to store radionuclides. Moni~oring ofa:iremissfons for the 218sW-4B w:ii~ cajssons win be performed using fourexisti_11g ambient air monitors (N-5_55, N-457, N-964, and N-433) that are maintained aji 11~ facility monitors in the WOW A,l:'ea. In addition an alternate monitoring lllethod is proposed to measure emissions for each caisson individually. Each caisson is equipp¢d with a passive HEP A filter as the abatement control technology.

· An alternate monitoring method is·approved for use forthe continuous and PCM monitoring requirements: Annually, a smear will be taken upstre:am of the HEPA filter as a contamination ·iU:di¢atcit. If detectable contamination is discovered, a smear.will be taken downstream of the HEPA filter as an abatement verification sample. If contamination above 20 dpm/100cm2 alpha or 1000 dpm/100cm2 beta/gamma is found downstream of the HEPA filttir, tlie s6u1w of the downstream co11taftl.ifta_ti_on will be inve:stiga.ted ai).d cO:rtec_teci (WAC 246-247-030( 17)) ..

6) ANNUAL TRENDING OF NEAR FACILITY MONITORING DAT A

The near facility monitoring network data for stations N433, N457, N555, and N964 win be trended on an annual basis to verify continued low emissions from the caissons (WAC 246-247:.030( 17)) ..
