SCOPE OF SERVICES

SCOPE OF WORK
ECOTEC is currently performing all the monitoring, sampling, testing, and reporting being proposed naer the variance. We intend to keep doing so and use the existing monthly, quarterly, and biannu nonitoring, sampling, and testing as partial fulfillment of the variance requirements. This scope of worl detines the additional monitoring, sampling, testing, and reporting necessary. We assume that the variance will be in place for approximately 6 additional months (through Dec 2023) and have used that time frame for the gap analysis between the needs for the variance and the existing monitoring, sampling, testing, and reporting
Perimeter Probe Monitoring
Currently ECOTEC is monitoring the probes monthly, the variance requires probes to be monitored at least every two weeks. The probes will be monitored at least once more per month, as necessary to monitor every two weeks.
Perimeter Probe Sampling and Testing
Currently ECOTEC samples and obtains laboratory testing of one probe each quarter. The variance requires at least one probe to be sampled and tested every two weeks. If there is landfill gas found in more than one probe, we may need to sample and laboratory test more than one. ECOTEC will sample and laboratory test one probe every two weeks and will notify the City if additional sampling and testing becomes necessary.
Ambient Air Monitoring
Currently ECOTEC samples and obtains laboratory testing of ambient air twice a year. The variance requires ambient air sampling and testing at least every two weeks along the southern boundary.
ECOTEC will sample and laboratory test ambient air along the southern boundary every two weeks.
Wellhead Monitoring
Currently ECOTEC is monitoring the wellheads monthly, the variance requires wellheads to be monitored at least every two weeks. The wells will be monitored at least once more per month, as necessary to monitor every two weeks.
Integrated Surface Monitoring
Currently ECOTEC performs integrated surface monitoring of each of the established grids each quarter.
The variance requires that monitoring be performed at least every two weeks. The site has approximately 100 grids, each approximately 50,000 square feet in area. Each grid must be monitored over a continuous 25-minute period while a field technician walks a prescribed path over the grid. The monitoring shall be done not more than 3 inches above the surface of the landfill and only when meteorological conditions meet the requirements for wind speed and precipitation. Monitoring must be conducted on days when there had been no rain during the preceding 72 hours. Monitoring shall be discontinued if instantaneous wind speeds are greater than 10 miles per hour (mph), or if the average wind speed over a 15-minute period exceeds 5 mph. When the weather is permitting ECOTEC will monitor each grid every two City of Riverside-Tequesquite Landfill Variance Monitoring June 2023.doc Recotec
Integrated Surface Sampling and Testing
Currently ECOTEC performs integrated surface sampling and laboratory testing for two grids each quarter. The variance requires that sampling and testing be done for at least two grids and up to 10% of the grids that are measured with more than 25ppmv TOC at least every two weeks. ECOTEC will sample and laboratory test two girds every two weeks and will notify the city if additional sampling and testing becomes necessary.
Instantaneous Surface Monitoring
Currently ECOTEC performs instantaneous surface monitoring of each of the established grids each quarter. The variance requires that monitoring be performed at least monthly. The site has approximately 100 grids, each approximately 50,000 square feet in area. Each grid must be monitored over a continuous 25-minute period while a field technician walks a prescribed path over the grid. The monitoring shall be done not more than 3 inches above the surface of the landfill and only when meteorological conditions meet the requirements for wind speed and precipitation. Monitoring must be conducted on days when there had been no rain during the preceding 72 hours. Monitoring shall be discontinued if instantaneous wind speeds are greater than 10 miles per hour (mph), or if the average wind speed over a 15-minute period exceeds 5 mph. When the weather is permitting ECOTEC will monitor each grid every month.
Reporting
Currently ECOTEC provides monthly monitoring and quarterly 1150.1 reports. With monitoring, sampling and testing being performed every two weeks we propose to report on the same basis. The existing reports will continue to be prepared and a more concise supplemental report that document the monitoring, sampling, and testing done each week will be provided to the city each week. The period will be Wednesday through Tuesday of the week. Each report shall include a summary of what monitoring, sampling and testing was completed, a separate discussion of each task completed, summary tables of field measurements and laboratory analytical results, and a site map showing the locations of all monitoring points.
