Mr. Kwasi Badu-Tweneboah, Ph.D, P.E., F.ASCE Geosyntec Consultants, Inc. September 13,2016 Page 2 Independent, third-party accreditation means that our management systems have been evaluated and have been found to conform to ASTM D7036 - a quality management standard that is directly applicable to source testing and a requirement for all Part 75 test programs. As a result, the data quality objectives necessary to produce reliable measurement results will be achieved. Proposed Scope of Services TRC will provide the labor, equipment, and technical expertise required to conduct your testing program as outlined below. The testing will be conducted at a landfill located in Indian River County by an Environmental Scientist. The actual mobilization, testing and equipment set-up and sampling, and demobilization will be conducted over a one-day schedule. All testing shall be conducted in one mobilization. The actual scope of work is to consist of the collection of landfill gas samples from the common header of the flare skid at a location prior to any condensate removal system at the Indian River Landfill. Samples will be collected into 6 or 8 liter SUMMA passivated canisters (supplied by an analytical laboratory), pre- charged halfway with Helium, in accordance with EPA Method 25C protocols. Three samples shall be collected at this location. The budget includes shipment of samples to and from an analytical laboratory (2-day air with tracking labels)for analysis via EPA Methods 3C and 25C. Geosyntec or the landfill owner shall supply a landfill gas analyzer to purge the sampling system and verify the validity of the landfill gas (must contain less than 5%oxygen or 20% nitrogen)just prior to sample collection. TRC will perform the tests summarized in the following table(s): Table 1: Test Program Requirements, Flare Skid Parameter Method Samples D ratnl)n Comment NMOC EPA Method 25C 3 15 to 20 Samples collected in triplicate and averaged Oxygen (02) EPA Method 3C 3 15 to 20 Samples collected in triplicate and averaged Nitrogen (N2) EPA Method 3C 3 15 to 20 Samples collected in triplicate and averaged Methane (CH4) EPA Method 3C 3 15 to 20 Samples collected in triplicate and averaged Carbon Dioxide (CO2) EPA Method 3C 3 15 to 20 Samples collected in triplicate and averaged Should Geosyntec determine that additional sampling is required from the new section of the landfill, installed in 2013, Cell I of Segment 3 Expansion, then an additional nine samples will be collected from the 11-acre section. These samples shall be collected by placing nine landfill gas probes in the landfill using a pilot probe inserted with a front-end loader. These samples shall be placed in predetermined locations, marked and flagged by Geosyntec. The front-end loader and operator shall be supplied by the landfill facility. Samples will be collected 24-hours following probe placement into 6 or 8 liter SUMMA Proposal Number 264523.9990
