<br />(b) Not applicable. American Soda's mining operations will not result in acid <br />mine drainage. <br />(16) Cased Solution Mining Wells <br />QA/QC measures employed during construction of the solution mining wells <br />will be provided by mechanical integrity testing (MIT) of the wells prior to <br />operation. MIT will be demonstrated by a combination of methods, including <br />cementing records, pressure testing, well bore logs, and cement bond logs. <br />Guidelines for MIT, as established in 40 CFR 146.8, have been included with this <br />document as Attachment 5. <br />Well Field Piping <br />Construction criteria establishing QA/QC measures have been included with <br />this document as Attachment 6. The attached documentation provides the codes <br />and standards for selection, testing, preparation, and installation of the well field <br />piping. <br />Ponds <br />QA/QC measures to be employed for the 13-acre evaporation pond will be <br />submitted to the DMG as a technical revision prior to pond construction. <br />Specifications and construction criteria providing QA/QC measures for the 1- <br />acre stormwater retention pond have been submitted to the DMG as a technical <br />revision by letter dated April 16, 1999. It is not anticipated that this pond will <br />contain toxic or acid-forming materials as a part of the mining process. <br />Additional information can be found in the 112 Permit Application, Exhibit D, <br />Section 2.4, Ponds. <br />Processing Facility <br />QA/QC measures employed at the Piceance Site processing facility include all <br />systems that could provide containment in the event of a spill. These structures, <br />including the stormwater retention pond and the V-ditches that serve the pond, <br />have been designed to contain a spill from the largest tank on site. Smaller spills <br />will be managed with floor sumps in the processing area, chemical absorbents, <br />and preliminary response measures. Employees will be trained to effectively <br />manage spills of this nature. Additional QA/QC measures are addressed in the <br />Preliminary Response Plan. <br />(1~ (a) Site specific soils information is provided in the 112 Permit Application, <br />Exhibit I. Soils stockpiling is addressed in the Reclamation Plan, Section 4.0, <br />Development and Operations. <br />(b) Asite-specific soils description is provided in the 112 Permit Application, <br />Exhibit I. A soils survey map is included in Exhibit I, Figure I-1. Additional <br />A-6 <br />
