OSHA Instruction CPL 2.87 FEB 20, 1990 Directorate of Compliance Programs SUBJECT: Inspection Procedures for Enforcing the Excavation Standards - 29 CFR 1926, Subpart P. A. Purpose. This instruction establishes inspection procedures and provides clarification to ensure uniform enforcement of the Excavation Standards. B. Scope. This instruction applies OSHA-wide. C. References. 1. Construction Safety and Health Standards, Subpart P., 29 CFR 1926.650, 651, and 652.D. Cancellation. OSHA Instruction STD 3-14.1, October 30, 1978, Citation Policy - Specific Trenching Requirements, is canceled. E. Action. Regional Administrators and Area Directors shall ensure that the guidelines in this instruction are followed and that compliance officers are familiar with the contents of the standard. F. Federal Program Change. This instruction describes a Federal program change which affects State programs. Each Regional Administrator shall: 1. Ensure that this change is forwarded to each State designee.G. Background. The Occupational Safety and Health Administration after 15 years of experience involving the adopted Federal standards for covered employees in the construction industry (36 CFR 25232 December 30, 1971) issued revised rules for Subpart P. to 29 CFR 1926 (54 CFR 45894 October 31, 1989). 1. These rules have been reviewed by the Advisory Committee on Construction Safety and Health (ACCOSH) and many of the changes reflect their recommendations and those of other interested parties.H. Inspection Guidelines (Compliance Procedures). 1. Excavation Protection Programs. This standard provides requirements which allow employers flexibility in developing programs that provide effective protection for employees working in excavations. In addition to the standard itself, the preamble provides further guidance and rationale for changes in the existing standard.I. Training. Field inspection procedures must be modified to reflect the more technical nature of soils classification and protection systems requirements of the new standard. To classify soils properly, visual and manual tests must now be performed. It is imperative that CSHOs be trained in the techniques used in these tests. The training program will consist of detailed instructions on the new standard and the compliance directive. 1. Train-the-trainer sessions on the new standard will be conducted at the OSHA Training Institute. These trainers will then conduct sessions for their respective Regional and Area Offices.J. SAVEs. Existing SAVEs for 29 CFR 1926.651 and 1926.652 as found in the existing Construction SAVEs Manual, OSHA Instruction CPL 2.34, shall not be used for citation of excavation or trenching violations after March 5, 1990. The attached draft SAVEs are provided for interim use and may be modified, as deemed appropriate, at the discretion of the Regional Administrator, to accommodate local circumstances, until the final SAVEs are published and distributed.
