Chemical Waste Landfill Annual Post-closure Care Report Calendar Year 2014.

摘要

The purpose of this CWL Annual Post-Closure Care Report is to document monitoring, inspection, maintenance, and repair activities conducted during CY 2014 in accordance with Attachment 1 of the PCCP (NMED October 2009 and subsequent revisions). This annual report documents PCCP activities conducted from January through December 2014 and fulfills the PCCP requirement for annual reporting to the New Mexico Environment Department (NMED). The PCCP requires monitoring, inspection, and maintenance/repair activities that must be documented and reported for each CY. Monitoring activities include semi-annual groundwater monitoring for specific volatile organic compounds (VOCs) and metals, and annual vadose zone soil-gas monitoring for specific VOCs. Inspection activities are required for the following components: final cover (vegetation and surface); storm-water diversion structures; monitoring networks and sampling equipment (groundwater and soil-gas); and security fence, locks, gates, signage, and survey monuments. The CWL final cover is a vegetative at-grade soil cover, or evapotranspirative (ET) cover.
