STATEMENT OF UNDERSTANDING AND APPROACH
ECOTEC understands the need to routinely monitor each extraction well, gas conveyance line and the total flow entering the flare. We believe in proactive tuning and performing preventative maintenance.
We also understand the security issues at this site and will be on site each week checking the perimeter and overall site conditions. ECOTEC has a good working relationship with Sun Power and routinely interact with their security staff. It is understood that preventative and other maintenance/repairs are not included in this project. Our experience preforming this work and coordinating with the City's maintenance and operations staff over more than a decade will ensure a smooth transition while keeping the site operational and in compliance. Monitoring the probes and surface emissions is required. Data from these monitoring events will be used for both regulatory compliance and indication of when there are gross tuning problems or problems with the landfill cover. Exceedances in probe readings or surface emission require costly remediation and additional monitoring efforts. Early detection and proactive tuning to avoid these problems is much more cost efficient. In the past fifteen years ECOTEC's statt has been successful in preventing surface and subsurface emissions from the TL. We intend to keep this up by following monitoring schedule below and not just collecting data for regulatory reporting but evaluating the data and preventing problems before they occur. ECOTEC understands that routine and preventive tunning/adjustments of the wellfield is part of this project and has taken that into account in our monitoring budget. After the photovoltaic facility was constructed and there were some regulatory rule changes ECOTEC worked with the City to prepare and submit a revised monitoring plan to South Coast Air Quality Management District (SCAQMD). The plan is currently in the approval process.
ECOTEC plans to continue providing regulatory liaison to facilitate the approval of the revised monitoring plan.
Continual Monitoring of the Flare
ECOTEC will monitor the flare continually for the following parameters and have the data stored digitally.
- Methane, Carbon Dioxide and Oxygen content in the landfill gas (LFG) entering the flare. - Flare and LFG temperature
- Gas flow rate
Weekly Monitoring of Critical Gas System Components
The following items will be monitored weekly to ensure sound operations and safety of the site.
Flare/Compressor Station Equipment, including all above ground gas pipe systems, structures, fluid levels and condensate containment vessels.
- Flare station operation
LEG system for condensate leaks
Manual condensate storage traps shall be observed for condensate level and leaks.
Site security, perimeter fence condition and overall appearance Semimonthly Monitoring of header Sample points
Header sample points will be monitored semimonthly to aid in system tuning and identify locations of poor performance, excessive pressure drop or leakage in the extraction system.
Monthly Monitoring and Reporting
ECOTEC will monitor and provide the following reports on a monthly basis to ensure effective tuning and communication of site conditions with the City.
- LFG extraction wells, monitoring and tuning. After each monitoring event is completed, well flow rate or vacuum adjustments for each well will be evaluated and implemented. Adjustments shall consist of varying the well's individual flow control valve as needed. After each adjustment is City of Riverside-Tequesquite Landfill RFP 2097 June 2021.doc ecetec
performed, the system shall be allowed to reach equilibrium before any additional adjustments are made. Follow-up monitoring will be conducted, and extraction wells shall be adjusted in response to system balancing on an as needed basis. The goal is to achieve the highest MMBTU value possible while meeting regulatory compliance.
Landfill Subsurface Perimeter Probes Monitoring
Monitoring and Maintenance reports will be completed documenting the well, probe and condensate trap readings. All monitoring and other activities that were undertaken during the month will be documented and any security, safety or operational concerns found will be delineated in both written form and with a picture (where possible) to help the City see the site conditions. The report shall include recommendations regarding maintenance repairs and/or system modifications that ECOTEC feels would be useful. Additionally, weekly flare logs with shutdown and startup information will be included.
Drainage devices shall be monitored, and their condition will be reported. - The automatic shutdown feature of the flare will be tested to ensure the system shuts down as designed and LFG is not vented when the flare is off.
Quarterly Monitoring and Sampling for 1150.1
ECOTEC will provide all SCAQMD Rule 1150.1 monitoring and reporting for the TL site. We fully intend to advise the City in a timely fashion should we find results that are potentially sensitive as soon as they are received. Such activities as surface maintenance to address desecration and settlement cracks will be detailed in the monthly and quarterly reports.
In a similar fashion the teams experience with compliance for SCAQMD Rule 1150.1 enables us to avoid problems with operating the gas collection system. We intend to keep the system at maximize methane production and perform compliance monitoring. Additionally, ECOTEC has coordinated with the City to revise the 1150.1 monitoring plan to accommodate the new Photovoltaic system. The plan is in the approval process.
All work will be performed in accordance with SCAQMD Guidelines for Implementation of Rule 1150.1
Instantaneous Surface Monitoring (quarterly)
The entire surface of the landfill has been divided into monitoring grids. Each grid measures approximately 50,000 square feet in area. The monitoring grids shall be used for both instantaneous and integrated surface monitoring/sampling. Instantaneous measurements of TOC concentrations immediately above the surface of the grids shall be obtained using a portable flame ionization detector (FID), which meets Guideline specifications. The probe of the FID must be held within 3 inches of the landfill surface while traversing the monitoring grids. A surface inspection shall also be performed during instantaneous surface monitoring to identify cracks or fissures in the landfill cover that could be potential pathways for LFG to escape to the atmosphere. Surface areas of the landfill at which total organic compound (TOC) concentrations exceed 200 parts per million by volume (ppmv) shall be marked with flags, identifying the areas of remediation. To initiate remediation, the City Project Manager of the landfill shall be notified of exceedance areas, Instantaneous Surface Monitoring (ISM) Data Sheets shall be distributed to appropriate personnel. Following implementation of mitigation measures, exceedance areas must be re-tested Consultant shall notify the City Project Manager, in writing, of any outstanding exceedances at the end of each month.
Integrated Surface Sampling (quarterly)
One integrated surface sample will be collected from each of the established sampling grids during each sampling event. Each grid measures approximately 50,000 square feet in area. Each integrated surface City of Riverside-Tequesquite Landfill RFP 2097 June 2021. doc ecetec
sample must be collected over a continuous 25-minute period while a field technician walks a prescribed path over the sampling grid. The samples shall be collected not more than 3 inches above the surface of the landfill. Samples must be collected only when meteorological conditions meet the requirements for wind speed and precipitation found in the Guidelines. Sampling must be conducted on days when there had been no rain during the preceding 72 hours. Sampling 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. ECOTEC working with the regulatory agency will ask for a variance to exclude this type of sampling since the SEM-500 will be used during the Instantaneous sampling and that data can be used for the Integrated sampling.
Ambient Air Sampling (semiannual)
Ambient air sampling, including field procedures and equipment, shall be conducted in accordance with Guidelines and the approved Compliance Plan for TL. Ambient air samplers must be positioned at the perimeter of the landfill to collect air samples representative of upwind (i.e., background) and downwind (i.e., air that has passed over the landfill surface) conditions at the site.
Sighting of ambient air sampler locations must be based on evaluation of historic wind monitoring data collected at the landfill. Sampler locations shall be established to provide good meteorological exposure to the predominant offshore and onshore win flows. Ambient air samplers are operated to meet SCAQMD design criteria and performance specifications found in the Guidelines. Light-sealed boxes containing individual 10-liter Tedlar sample bags are housed within each weather-tight, ambient air sampler.
Ambient air sampling will be conducted over two simultaneous 12-hour periods. One sample will be collected for each 12-hour period from each upwind and downwind sampler and will be forwarded to the laboratory for analyses.
Ambient air sampling will be conducted when weather conditions conform to the meteorological criteria specified in the Guidelines. These include:
No rainfall during the sampling period
- Average wind speeds not exceeding 15 mph during any 30-minute period. - Instantaneous wind speeds not exceeding 25 mph
LFG Monitoring (quarterly)
LFG samples shall be collected from the main LFG header line entering the compressor/flare station. At the site, a LFG sample will be collected in a 10-liter Tedlar bag (enclosed in a light-sealed box) over a 10- minute period.
Perimeter Probe Sampling (monthly)
Perimeter probe sampling shall be conducted using procedures descried in the Guidelines. Prior to collecting a sample, each probe must be evacuated until the TOC concentration remains constant for a minimum of 30 seconds, as indicated on a LANDTEC GEM 2000 or 5000 instrument. Each perimeter probe sample shall be monitored monthly, lab samples will be taken quarterly.
In addition, each monitored probe containing greater than 2% Methane shall require ISM Monitoring on the area between the probes and refuse footprint. This task will be performed at the same interval as probe monitoring.
Quarterly Reporting
Within 30 days of the end of each quarterly period, ECOTEC shall prepare site specific Draft Rule 1150.1 Quarterly Monitoring Report for the review by the City. Upon receipt and incorporation of comments, City of Riverside-Tequesquite Landfill RFP 2097 June 2021 doc ecetec
Consultant shall submit a finalized report for the City of Riverside which will be submitted to SCAQMD within 45 days of the end of each quarter. Each report shall include an executive summary, 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. Field data sheets and laboratory analytical reports will be included as appendices.
Rule 1150.1 Laboratory Analyses
ECOTEC will use Atm AA Inc. to perform the laboratory analyses needed for 1150.1 rule. All samples will be analyzed in accordance with the EPA prescribed methods and within the required holding times.
Integrated Surface Sample Analyses
A minimum of two samples or 10% of all exceedances, whichever is greater, per event shall be submitted for laboratory analysis within 72 hours of collection for Methane, total gaseous non-Methane organic compounds (TGNMO), and core group toxic air contaminants.
Ambient Air Sample Analyses
Upwind and downwind air samples shall be analyzed within 72 hours of sample collection for Methane, TGNMO, and core group toxic air contaminants.
LFG Sample Analyses
LFG samples shall be submitted for laboratory analysis within 72 hours for fixed gases (i.e., Methane, carbon dioxide, oxygen, and nitrogen), TGNMO, hydrogen sulfide, and core group toxic air contaminants.
Perimeter Probe Sample Analyses
A maximum of three samples from the site must be collected and sent for laboratory analyses from those probes showing a TOC concentration in excess of 5% by volume. If no probes are found, through field measurement, to have TOC concentrations above 5% by volume, one sample shall be collection from the probe showing the highest TOC concentration during each event and submitted for laboratory analysis.
Samples must be analyzed within 72 hours of collection for Methane, Carbon Dioxide, TGNMO, and core group toxic air contaminants.
Periodic "As Necessary" Tasks
Regulatory Liaison Support
Should it be necessary ECOTEC will provide the City with regulatory liaison support to address any questions SCAQMD has about the reports, data, conclusions derived or sample analysis. Additionally, ECOTEC will provide time to discuss revising the monitoring plan with the City's Utility department to accommodate the solar farm and reduce monitoring.

SCOPE OF WORK
ECOTEC is currently performing all the monitoring, sampling, testing, and reporting being proposed under the variance. We intend to keep doing so and use the existing monthly, quarterly, and biannual monitoring, sampling, and testing as partial fulfillment of the variance requirements. This scope of work defines 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 equires at least one probe to be sampled and tested every two weeks. If there is landfill gas found i nore than one probe, we may need to sample and laboratory test more than one. ECOTEC will sampl 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 weeks.
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.
