III. Environmental Setting, Impacts, and Mitigations L. Public Health and Safety Mitigation Measure L.I. Proposed as Part of the Project (a) The landfill does not accept any special wastes that potentially may contain elevated levels of hazardous substances such as: • Chemicals or chemical sludges • Drugs • Free liquids,including residues in containers or paint cans • Bag house or air scrubber wastes • Tank cleaning sludges • Contaminated soil (b) Dust control procedures specified in the Site Operations Plan shall be applied to handling of all wastes received at the landfill. Identified by this EIR (c) Dust exposure of site workers should be periodically measured to determine if recommended exposure levels are exceeded. Documentation of the results of the measurements should be provided to the LEA and placed in the administrative file. (d) Additional engineering controls should be implemented by the site operator,if needed,to control dust emissions. Such controls might include wind screens near the unloading areas or the use of dust suppressants. (e) If the above engineering controls cannot reduce employee dust exposure below an acceptable level as determined by the LEA, site personnel at risk should be supplied with gloves,coveralls,eye protection, and respirators. OSHA regulations contained in 29 CFR, Section 1910.134,describe the required Respiratory Protection Program. It should include medical exams,monitoring of worker exposure, and training in proper respirator use. Special training and monitoring emphasis should be placed on the additional hazards resulting from respirator use,such as possible heat stroke. The Respiratory Protection Program should determine when and where masks should be worn and how their use should be monitored. It should be the intent of such a program that personal protective equipment such as dust-filtering respirators should be necessary to provide protection supplemental to that provided by the engineering controls. (f) Wastes must not leave the landfill site on workers clothing. Various methods could be employed to prevent exposure of people off-site to waste carried by workers'clothing. This EIR suggests the following measures: • working clothes should be left behind at the landfill and cleaned by the operator; • shower facilities and changing areas should be provided at the project site so that workers do not carry material off-site;and III.L.15
