Waste description

Richland, Washington
Conditions:
1
a
i Complete sufficient characterization of the waste stream to demonstrate that the waste stream is within the treatability envelope of 200 Area ETF as specified in Tables C1 and C2 of the delisting petition dated November 29, 2001, as amended. Results of the waste stream characterization and the treatability evaluation must be in writing and placed in the facility operating record, along with a copy of Tables C1 and C2 of the November 29, 2001 petition, as amended. Waste stream characterization may be carried out in whole or in part using the waste analysis procedures in the Hanford Facility RCRA Permit, WA7 89000 8967;
ii Prepare a written waste processing strategy specific to the waste stream, based on the ETF process model documented in the November 29, 2001 petition, the March 31, 2021 modification request, and Tables C1 and C2 of the November 29, 2001 petition, as amended. For waste processing strategies applicable to waste streams for which organic envelope data is provided in Table C2
of the November 29, 2001 petition, as amended, Energy shall use envelope data specific to that waste stream, if available. Otherwise, Energy shall use the minimum envelope in Table C2.
b Energy may modify the 200 Area ETF treatability envelope specified in Tables C1 and C2 of the November 29, 2001 delisting petition, as amended, to reflect changes in treatment technology or operating practices upon written approval of the Regional Administrator. Requests for modification shall be accompanied by an engineering report detailing the basis for a modified treatment envelope.
Data supporting modified envelopes must be based on at least four influent waste stream characterization data points and corresponding treated effluent verification sample data points for wastes managed under a particular waste processing strategy.
Treatment efficiencies must be calculated based on a comparison of upper 95 percent confidence level constituent concentrations.
Upon written EPA approval of the engineering report, the associated inorganic and organic treatment efficiency data may be used in lieu of those in Tables C1 and C2 for purposes of condition 1ai.
c Where operation of the 200 Area ETF for purposes of gathering data supporting a modified treatability envelope pursuant to Condition 1b requires operation outside of an existing treatability envelope or where a new treatability envelope is to be proposed, Energy may request interim approval to conduct such demonstration testing for purposes of developing a new or modified treatability envelope.
Such a request must include the following documentation:
i An Engineering Report documenting the basis for a modified treatability envelope. The Engineering Report shall, based on best available information, document that operation of the 200 Area ETF during the period of interim approval can be reasonably expected to produce treated effluent satisfying the delisting levels in Condition 5. The Engineering Report shall include, but is not limited to, engineering calculations, process modelling results, or performance data provided by equipment manufacturers;
ii A demonstration test plan documenting the following:
A The quantity and characterization of the waste stream to be used in conducting demonstration testing, and information that will be included in the waste processing strategy required by Condition 1aii for the demonstration testing. The test plan shall document, to a reasonable degree of certainty, that data gathered from the demonstration testing will be suitable for use in modifying the treatability envelope pursuant to Condition 1b. The test plan may include provisions for spiking the demonstration test waste feed to ensure that a waste feed meeting the requirements of the test plan is available;
