Document Description
The Removal Action Workplan (RAW) has been prepared to address the removal of methane gas at the proposed Rosa Parks Elementary School property. The Corona Norco Unified School District (CNUSD) has elected to pursue the construction of the school, and therefore has prepared a RAW. The draft RAW presents an evaluation of several removal action alternatives to address the presence of methane and identifies preferred alternative. Due to the concentrations and pressures of methane detected, and the depth of the detections, the RAW proposes a Passive Methane Venting System (mitigation system) as the preferred alternative. The selected methane control measures include a sub floor membrane barrier, a passive venting system, and permanent sampling and detection probes above the membrane. An Operation and Maintenance (O&M) Agreement will ensure the school district will implement on-going operation, monitoring, data acquisition, reporting, and maintenance activities. The control measures, proposed under this alternative, are in accordance with DTSC's Advisory on Methane Assessment and Common Remedies at School Sites (June 2005) and meet or satisfy all applicable or relevant and appropriate requirements (ARARs) as identified in the RAW.

Notice of Exemption
Exempt Status
Other
Type, Section or Code
Section 15061(b)(3)
Reasons for Exemption
The RAW includes Methane Mitigation Design Plans, Methane Mitigation Specifications, an Engineering Evaluation/Cost Analysis, an Engineers Cost Estimate, a Health and Safety Plan, a Construction Quality Assurance Plan, a Removal Action Implementation Plan, and an Operation and Maintenance Plan. The project will not have a significant effect on the environment due to depth of contaminant, low pressure of contaminant, and controlled manner in which the mitigation system will be constructed, operated and monitored. The proposed Rosa Parks Elementary School site is not on the Hazardous Waste and Substances Sites List, nor is it located in a sensitive cultural or biological resource area.
