The NRCS CPS 313, Waste Storage Facility, has been revised and is available for comment through Monday, July 10, 2017.  As a result of this revision, liner requirements were moved from 313 into separate liner standards. Additionally, a separate temporary stacking was created; see a list of all new standards below. All of these standards are open for comment and are contained in the single document provided below for your editing & reviewing ease.

Background:  The Wisconsin CPS 313 standard was updated because changes were made to the National 313 standard.  Wisconsin can alter the national standard to create a Wisconsin standard, but the new Wisconsin standard must meet or exceed the requirements listed in the National standard.  The draft Wisconsin standard has been formatted to assist the reviewer in distinguishing National standard requirements from Wisconsin requirements.  National standard requirements are written in black with dashed underlining; Wisconsin specific language is blue. These distinctions will be removed in the final version.

Standard Formatting:  All NRCS standards are being reformatted to be compliant with the Plain Language Initiative (508 compliant).  This reformatting removes the two column format and the number/letter category designation that was present in previous standards.

New Practice Standards:  The National Standard removed the liner requirements from the 313 standard and moved them to Pond Sealing or Lining- Compacted Soil Treatment (520), Pond Sealing or Lining- Flexible Membrane (521) and Pond Sealing or Lining- Concrete (522).  The language in the previous 313 standard that dictated requirements for the liners has been moved to the appropriate liner standard.  From the current WI 313 standard, Table 1 (In Place Earth) remained in the 313 standard.  Tables 2 (Clay Liner) and 2A were moved to the 520 standard.  Tables 3 (Geomembrane) and 4 (GCL) were moved to the 521 standard.  Table 5 (Concrete Liner) and Table A (Reinforcing Steel) were moved to the 522 standard.  All associated requirements were also moved as appropriate.

Additionally, the temporary stacking requirements (Table 10- Temporary Stacking) and associated requirements were moved to a WI CPS 318– Short Term Storage of Animal Waste and By-Products.  This National standard was also altered to incorporate Wisconsin requirements.

Because of these updates and associated reformatting, a red-line markup does not effectively show changes and is not provided. We encourage you review these as entirely new documents.

WDNR and the Standard Oversight Council revision team will carefully consider all comments before finalizing an updated version of the practice standard.  Comments on Wisconsin criteria (blue) will receive a response from the SOC team. Comments on National criteria (dashed underline) will be noted, but receive no response, as Wisconsin must meet or exceed this criteria.
