This Health and Safety Plan (HSP) identifies the safety procedures to be conducted at the Los Angeles County Metropolitan Transportation Authority (MTA) Division 6 facility located at 100 Sunset Avenue, Venice, California. The site location is illustrated on Figure 1. This HSP is to be used in conjunction with the URS Injury and Illness Prevention Program (UPP)...[this] site-specific workplan has been prepared to address work activities for the soil and groundwater investigation to be conducted at the site in 2001. The soil and groundwater investigation will consist of soil sampling with monitoring well installation and sampling. A hollow stem auger drill rig will be used to complete soil sampling and monitoring well installation activities. Other activities planned for the investigation include concrete coring, monitoring well development, and sampling, and geophysical and boring location surveying. After the monitoring wells are installed, quarterly groundwater monitoring and sampling of the previously four and newly installed monitoring wells will be conducted at the site. This HSP identifies the safety procedures to be conducted while performing work activities at the MTA Division 6.
This workplan addresses work activities to be conducted for the soil and groundwater investigation at the Los Angeles County Metropolitan Transportation Authority Division 6...The objective of the investigation described in this work plan is to [i]nvestigate subsurface soil and groundwater conditions to further assess the lateral and vertical extent of the petroleum hydrocarbons and related fuel constituents identified in previous subsurface investigations.
This Phase II Investigation Work Plan discusses the field work and laboratory testing required to determine the extent of contaminated materials to be encountered during the construction of Stage 4 of the Chaska Flood Control Project. This work plan was developed in response to indications of potentially contaminated soils and groundwater (petroleum products, petroleum product and solvent odors, and dump/debris fill) encountered in several geotechnical soil borings advanced for geotechnical design purposes along the proposed levee and channel alignments. These borings were advanced for physical property testing rather than for contaminant analysis since contaminated materials and/or groundwater were not anticipated on these stages of the project. In addition, potential contamination sources were identified during a Phase I Environmental Site Assessment for these stages of the project. According to the Minnesota Pollution Control Agency (MPCA) document "Update on Property Transfer Cleanup Assistance", a Phase II Investigation Work Plan is required to determine if the potential sources of contamination identified during the Phase I Investigation are actually causing a release or threatened release of hazardous substances to the soil and groundwater at the project site. This work plan contains background information on the site; the scope of work for Task 1, Work Plan and Health/Safety Plan, Task 2, Field Investigation Work, and Task 3, Phase II Investigation Report. The report also describes the methodology that should be followed in conducting soil borings, hand auger borings, soil classification, soil sampling and chemical analysis, decontamination, soil headspace analysis, and chain of custody.
