Summary:  EPA is amending the Third Edition of the EPA-approved test methods manual "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846 which is incorporated by reference in § 260.11.  This amendment clarifies the temperature requirement for pH measurements of highly alkaline wastes and adds Update IIB Method 9040B (pH Electrometric Measurement) and Method 9045C (Soil and Waste pH) to EPA Publication SW-846.  SW-846 is a document that changes over time as new information and data are developed.  Advances in analytical instrumentation and techniques are continually reviewed and periodically incorporated into SW-846 to support changes in the regulatory program and to improve method performance.  Update IIB (Methods 9040B and 9045C) represent such an incorporation.  The intent of this amendment is to provide better and more complete analytical technology for RCRA testing in support of hazardous waste identification under the corrosivity characteristic.

State Authorization:  This rule is placed in RCRA Cluster V.  The State modification deadline is July 1, 1996 (or July 1, 1997 if a State statutory change is necessary).  These changes do not go into effect until States become authorized for them because this rule was promulgated under pre-HSWA authorities.  Only final authorization is available.

The State Revision Application must include applicable regulations, AG statement addendum, Revision Checklist 141, other associated checklists and other application materials, i.e. a program description and an MOA, as determined by the Regional office.
