2.2 Applicability

This document applies to all workers at N3B, including subcontractors, who generate, manage, treat, or store regulated waste at LANL as a waste generator or as a TSDF worker.

TSDF workers include personnel who manage, treat, or store regulated waste under the LANL HWP. All subcontractors must follow the requirements as set forth in their contractual agreements or subcontracts. Included in the contractual agreements is Exhibit F, Environment, Safety, and Health Requirements for Subcontractors; Exhibit G, Security Requirements for Subcontractors; and Exhibit H, Quality Assurance Requirements.

3.0 PROCEDURE DESCRIPTION

The Waste Acceptance Criteria (WAC) establishes requirements for waste acceptance at N3B TSDFs. Characterizing waste and planning for disposition of the waste are essential components of waste planning, requirements can be found in P409-0, Attachment 2.

TSDFs and facilities receiving N3B on-site generated wastes for packaging, repackaging, treatment, storage or disposal include Sanitary Wastewater Systems (SWWS), TA-54 Area L, and TA-54 Area G. These facilities routinely manage regulated non-hazardous waste, hazardous waste, low level waste (LLW), mixed low-level waste (MLLW), transuranic

RFP-0000300

(TRU) waste, and mixed transuranic (MTRU) waste. Other permitted facilities generate waste and do not routinely receive from other LANL on-site generators. TSDFs must comply with the conditions of this WAC, their individual Authorization Basis as applicable, and other operational requirements. These requirements may impact waste acceptance considerations such as Material at Risk (MAR), combustible loading, and other applicable considerations.

A Nonconformance Report (NCR) will be issued in accordance with N3B-P330-6, Nonconformance Reporting, to any waste generator that discharges or transports a waste stream that does not meet the criteria outlined in this document or for which a WAC exception was not approved. The Waste Certification Official (WCO) must be notified when an NCR or an issue is entered into the Contractor Assurance System (CAS) regarding non- TRU waste streams, including hazardous waste, NMSW, etc. Similarly, the N3B TRU Program Manager must be notified when an NCR or an issue is entered into CAS regarding M/TRU. WCO and/or TRU Program Manager concurrence for corrective actions must be obtained in the NCR and CAS before the issue is closed.

3.1 Waste Acceptance Process

Waste must be characterized in accordance with N3B-P409-0, Attachment 2 requirements. A waste stream profile (WSP) must be completed and approved before waste is accepted at a TSDF. Waste Disposition must submit electronic requests for waste acceptance through Waste Compliance and Tracking System (WCATS), along with the appropriate forms. Once the waste has been adequately characterized, packaged, and labeled, a Waste Disposition Request (WDR) is initiated in WCATS. The WDR is the tool used to notify the receiving facility of the type and contents of a proposed shipment. If the receiving facility determines that the shipment meets the facility’s WAC, the facility approves the waste receipt.

For instructions on creating waste IDs, see the WCATS User’s Manual, Section 5.2.1, Waste Item Identification Using the Mobile Device. For instructions on creating the WDR, see Section 7.2, Submitting a Waste Disposition Request. For help regarding waste data issues on WCATS, send an e-mail to wastehelp@lanl.gov or call the waste help call center at (505) 665-2494.

3.2 Dumpsters and Office Trash

N3B has many dumpsters on-site that are designated for compactable sanitary solid waste trash only. These dumpsters are sent directly to the Los Alamos County Transfer Station.

The items listed in Table 1, Municipal Trash Restrictions, should never be placed into a trash dumpster or office trash receptacles.

Table 1. Municipal Trash Restrictions

Radioactive waste Hazardous waste Asbestos or asbestos contaminated materials

PCB waste PCB containing items Waste labels (e.g., rad, haz)

New Mexico Special Waste TSCA regulated waste Universal waste

Corrosives Chemical containers Flammable materials

Recyclable materials Classified, sensitive, PII, UCNI, OUO, etc. info

Contact Waste Disposition for assistance with disposal of any of these items.

3.3 Technical Area 54 (TA-54)

If hazardous waste will be stored in a permitted storage area at TA-54, it must meet the LANL HWP Waste Analysis Plan before it is shipped to the storage area. Newly generated mixed waste must be adequately characterized for off-site treatment and disposal so that the TA-54 TSDF can be operated in a turnkey mode. (i.e., mixed waste is received and shipped without further consolidation to packaging, or characterization). There are prohibitions and restrictions on the chemical and radiological characteristics of the waste for acceptance into TA-54 TSDFs as listed in Table 2, Chemical Prohibitions and Restrictions.

Table 2. Chemical Prohibitions and Restrictions

Chloric acid >10% Fuming nitric acid >86% Perchloric acid >60% weight

Sodium dichloro-s-triazinetrione

Calcium hypochlorite >50% weight Ammonium permanganate

Peroxide

• Hydrogen peroxide sol.

>52%

• Other peroxide >10 ppm

Class-3 oxidizers

• >1 L per item

• Significant rad component

Flammable liquid/gas

• >55 gallons

• Significant rad component

Potassium dichloro-s-triazinetrione (potassium dichloroisocyanurate)

Mono-(trichloro)-tetra- (monopotassium dichloro)-penta-s-triazinetrione

Ammonium perchlorate (particle size >15 μm)

Sodium bromate Guanidine nitrate Tetranitromethane

Ammonium dichromate Potassium chlorate Sodium chlorite

Class-4 oxidizers Sodium chlorate Potassium bromate

DOT Class 1 as defined in 49

CFR 173.50

Explosives

• Unreacted constituents

• >1% explosive solid

• >10% explosive in solution

Dioxins (case-by-case determination)

Unknown wastes Classified nonradioactive waste Un-sealed containers

Note 1: An insignificant radiological component is defined as having less than 0.1% of the activity listed in Appendix B of 40 CFR 302.4, Designation of Hazardous Substances.

Note 2: A Class-3 oxidizer is an “oxidizer that will cause a severe increase in the burning rate of combustible materials with which it comes in contact or that will undergo vigorous self-sustained decomposition due to contamination or exposure to heat” (National Fire Protection Association [NFPA] Standard Number 430).

Note 3: A Class-4 oxidizer is an “oxidizer that can undergo an explosive reaction due to contamination or exposure to thermal or physical shock. In addition, the oxidizer will enhance the burning rate and can cause spontaneous ignition of combustibles” (NFPA 430).

Note 4: If the particle size of ammonium perchlorate is less than 15 μm, it is classified as an explosive.

A WAC exception may be requested for restricted waste; however, the acceptability of a restricted waste will depend on the current storage capacity and the overall radiological and physical inventory of the storage area. Exceptions will be considered on a case-by-case basis. Exceptions will not be approved for explosives or Class-4 oxidizers. In addition, exceptions will not be approved for flammable liquids, flammable gases, or Class-3 oxidizers where the radiological component exceeds 100% of the Reportable Quantity (RQ).

The following waste types or materials must not be packaged with solid LLW destined for management at a N3B TSDF:

• Explosives

• Pathogens, infectious wastes, or other etiologic agents as defined in 49 CFR 173.134.

• Pyrophorics

• TRU/MTRU waste

Waste generators must use the fissile gram equivalent (FGE) values listed in Section 3.6.1.a, Contact-Handled Transuranic Waste, to determine fissile quantities in LLW containers.

Waste generators are not required to count the FGE content of natural and/or depleted uranium (i.e., uranium enriched to <0.93 wt% U-235) toward the criticality safety limits.

3.3.1 Area L

There are additional WAC requirements, in addition to the requirement for TA-54, for receipt of waste items into TA-54 Area L. Waste may be accepted into permitted storage areas in Area L if it is in compliance with the LANL HWP requirements. Area L is a less than Hazard Category III facility; radioactive waste accepted into Area L must be evaluated against the facility limits to ensure that Hazard Category III or higher quantities of materials are not brought into the facility.

Waste may be accepted from non-N3B generators such as LANL for storage in Area L. This waste must be fully characterized, profiled, and meet all of the requirements of Section 3.4 prior to acceptance. The waste must also meet all of the packaging and labeling requirements described in N3B-P409-0, Attachment 5. Any waste accepted into Area L must have a path to disposition. Waste from non-N3B generators that is accepted into Area L must be dispositioned in a compliant time-frame by the generator, otherwise N3B will disposition the waste to ensure compliance and will charge the generator. Waste that becomes non-compliant while in storage at Area L will be shipped back to the generator for management and/or remediation.

3.3.2 Area G

There are additional WAC requirements, in addition to the requirement for TA-54, for receipt of waste items into TA-54 Area G. TA-54 Area G, may receive M/TRU and M/LLW waste for storage, repackaging, and characterization. The following is a brief summary of TRU/MTRU waste acceptance criteria for TA-54. This summary is not to be considered all-inclusive. CH-TRU Waste Management Programs will determine acceptability before authorizing waste receipt into TA-54 Area G:

• TRU accepted for storage and/or treatment at TA-54 Area G is not required to meet current Waste Isolation Pilot Plant (WIPP) WAC requirements.

• TRU accepted for characterization and/or shipment at TA-54 Area G should meet current WIPP WAC requirements; however, this is not required. If TRU that is accepted for characterization and/or shipment is found to be non-compliant with the WIPP WAC, it may be transferred back to the generator for remediation, or added to an Area G treatment queue, which may drive additional cost to the generator.

• TA-54 Area G shall not accept D001 waste containing organic cellulosic materials, except as specifically authorized by CH-TRU Waste Management Programs.

• TRU/MTRU waste containing free liquids must be stored on secondary containment, in accordance with the LANL HWP.

• Mixed waste sealed sources may be accepted at TA-54 Area G. Such waste management is subject to the requirements of LANL HWP, Section 2.2.1[4]

– Sealed mixed waste sources that have a defense determination and meet the requirements of the WIPP WAC may be accumulated up to an annual volume of no more than one 55-gallon drum equivalent of mixed waste sealed sources.

– All mixed waste sealed sources described in the LANL HWP, Section 2.2.1 shall not be stored at the facility for longer than one year.

The technical safety requirements (TSRs) for TA-54 Area G impose package limits for fissile material. The fissile or fissionable isotope content in the plutonium-239 FGE of LLW packages must not exceed the values shown in Table 3, Plutonium-239 Fissile Gram Equivalent (FGE) Content for Low Level Waste (LLW) Packages.

Table 3. Plutonium-239 Fissile Gram Equivalent (FGE) Content for Low Level Waste (LLW) Packages

If Then

Packages are smaller than 55 gal., the total FGE must not exceed 10 g.

Drums are 55 gal. or larger, but are smaller than 90 ft3, the total FGE must not exceed 275 g.

Metal boxes are 90 ft3 or larger, the total FGE must not exceed 350 g.

The container is a Dumpster (total of all packages), the total FGE must not exceed 350 g.

The waste is uncontainerized LLW, the average FGE loading must not exceed

0.1 g/L.

Source: Criticality Safety Evaluation for the TA-54 Low Level Waste (LLW)

If more than 15 g of fissile isotopes is packaged together, it may constitute a fissile material under Department of Transportation (DOT) regulations and may not be acceptable for transport in a DOT industrial package.

3.3.2.a Area G Pit 38 LLW Disposal Limits N3B retains limited capacity for on-site disposal of LLW at TA-54 Area G Pit 38 under special circumstances and with prior approval from Department of Energy (DOE). Area G shaft disposal is not currently authorized. For waste to be classified as LLW, the concentration of alpha-emitting TRU radionuclides with half-lives greater than 20 years must not exceed 100 nCi/g of waste, and the waste cannot contain any hazardous or toxic constituents that would require it to be managed under RCRA or TSCA. TRU-contaminated waste cannot be disposed of at TA-54 Area G when the activity concentrations exceed 100 nCi/g. Operational waste that is disposed of a minimum of 3 m (9.8 ft.) below operational (current) grade must comply with the radionuclide concentration limits listed in Table 4, Reportable Radionuclides and Upper Limits. The DOE Office of Environmental Management – Los Alamos Field Office must approve the disposal of LLW in Pit 38.

3.4 LANL Facilities

3.4.1 Sanitary Waste Water System (SWWS) Acceptance Criteria

This facility is managed by LANL, and the LANL WAC will govern acceptability of waste for transfer to SWWS. All sanitary sewer waste discharged or transported to the LANL sewage plant must meet the WAC described in LANL P409-1, and summarized in this section. New waste streams or changes to existing approved WSPs require new analytical measurements (see Tables 6, 7, and 8 for all parameters). Waste Disposition must complete a new WSP and obtain approval from the SWWS WAC Committee before discharge or transport.

Samples for evaluation of contaminants must be taken as close to the point of discharge into the sanitary sewer collection system as possible. When sampling cannot be completed at the point of discharge, samples should be taken at the first available manhole or sampling port downstream from the point of discharge.

A sign designating the holding tank or septic tank system number must be provided at the tank location. Waste generators must provide for roadways to on-site holding tank and septic tank systems that are adequate for pump truck use with no restrictions to access. All septic and holding tanks and related equipment must be plainly visible and protected from any snow removal activities. Tanks must have adequate capacity to contain the sanitary flow from connected buildings. The Facility Operations Director must ensure new or upgraded installations are equipped with high-level alarms for holding tanks. The alarm light must be visible to building residents. All holding tanks and septic tanks without an approved WSP must be characterized before any pumping activities. It is the waste generator’s responsibility to meet all WAC requirements for holding tank and septic tank systems before pumping and transport of sanitary sewer waste to the SWWS plant. Waste generators must provide at least a 48-hour notice to SWWS plant personnel before sanitary sewer waste transport. To ensure the integrity of the SWWS plant and to maintain compliance with LANL’s NPDES permit, additional sampling (including, but not limited to, SWWS WAC parameters, RCRA parameters, and various metals) may be required for holding tank and septic tank systems that have not been pumped within the past 3 years.

3.4.2 TA-54-38 Radioactive Assay and Nondestructive Testing Facility (RANT) The RANT building and outdoor pad may receive WIPP-certified waste from facilities for storage and packaging of TRUPACT II containers for shipment to WIPP. This facility is managed by LANL, and the LANL WAC governs acceptability of waste for transfer to

RANT.

RANT consists of two permitted units, a container loading building, and an outdoor storage pad. The permitted units at RANT may receive hazardous or mixed waste containers in accordance with the LANL HWP, Section 3.3 (e.g., 55, 85 or 110-gallon drums, SWBs, or ten-drum overpacks). The building houses the indoor permitted hazardous waste storage unit, which includes the high bay and low bay portions of the building. The high bay is typically used to load TRUPACT-II containers.

The following is a summary of requirements for waste acceptance at RANT permitted TSDFs; however, the summary is not intended to be all-inclusive. CH-TRU Waste Management Programs will coordinate with LANL for the authorization to transfer waste to

RANT.

• RANT may accept and store waste in sealed NRC-certified Type B shipping containers and TA-54 West Outdoor permitted unit without secondary containment and weather protection.

• All other waste containers that are stored outdoors and are not being actively managed are protected from contact with precipitation using weather protective equipment and are on proper secondary containment, if necessary.
