OSHA State Plans: In Brief, with Examples from California and Arizona

Description: This report examines various state plans under the Occupational Safety and Health Act of 1970 (OSH Act), which authorizes states to establish their own occupational safety and health plans and preempt standards established and enforced by the Occupational Safety and Health Administration (OSHA). OSHA must approve state plans if they are "at least as effective" as OSHA's standards and enforcement. The report provides specific examples from California and Arizona

USAEC Airborne Radiometric Reconnaissance in Arizona, California, Nevada and New Mexico, 1953 to 1956

Description: From introduction: This is one of a series of three reports on airborne radioactivity surveys in the United States. The reports contain the 185 airborne anomaly maps issued by the U. S. Atomic Energy Commission as a result of the AEC's aerial surveying program conducted from March 1952 to June 1956; two ground reconnaissance maps of Utah also are included. Most of the reconnaissance was done in the western United States.

A Method for Estimating Ground-Water Return Flow to the Lower Colorado River in the Yuma Area, Arizona and California--Executive Summary

Description: Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that will permit an accounting of ground-water return flows from each side of the Colorado River in the Yuma reach. The estimates of return flow can be used by water-management agencies in determining return-flow credits for the States of Arizona and California.
