Section 7:27C-10.5 - CO[2] emissions offset project standards - landfill methane (CH) capture and destruction

(a) To qualify for the award of COoffset allowances, in addition to satisfying the other applicable requirements of this subchapter, an offset project that captures and destroys methane from landfills shall meet the requirements of (b) through (f) below.

(b) An offset project under this section shall occur at a landfill that is not subject to the New Source Performance Standards for municipal solid waste landfills, 40 CFR Part 60, Subparts Cc and WWW .

(c) The project sponsor shall provide a detailed narrative of the offset project actions to be taken, including documentation that the offset project meets the requirements of (b) above. The project narrative shall include:

1. Identification of the owners and operators of the offset project;

2. The location and specifications of the landfill where the offset project will occur, including waste in place;

3. Identification of the owners and operators of the landfill where the offset project will occur; and

4. Specifications of the equipment to be installed and a technical schematic of the offset project.

(d) The emissions baseline shall represent the potential fugitive landfill emissions of methane (in tons of CO[2] e), as represented by the methane collected and metered for thermal destruction as part of the offset project, and shall be calculated as follows:

where:

V = Volume of CH[4] collected (ft<3>);

M = Mass of CH[4] per cubic foot (0.04246 lbs/ft<3> default value at one atmosphere and 20 degrees Celsius);

OX = Oxidation factor (0.10), representing the estimated portion of collected CH that would have eventually oxidized to CO[2] if not collected; and

GWP = CO[2]e global warming potential of CH[4](28).

(e) Emissions reductions shall be determined based on potential fugitive methane emissions that would have occurred at the landfill if metered methane collected from the landfill for thermal destruction as part of the offset project was not collected and destroyed. COe emissions reductions shall be calculated as follows:

where:

V = Volume of CH[4] collected (ft[3]);

M = Mass of CH[4] per cubic foot (0.04246 lbs/ft<3> default value at one atmosphere and 20 degrees Celsius);

OX = Oxidation factor (0.10), representing the estimated portion of collected CH[4] that would have eventually oxidized to CO[2] if not collected;

C[ef] = Combustion efficiency of methane control technology (0.98); and

GWP = CO[2]e global warming potential of CH[4](28).

(f) An offset project under this section shall employ a landfill gas collection system that provides continuous metering and data computation of landfill gas volumetric flow rate and methane concentration. Annual monitoring and verification reports shall include monthly volumetric flow rate and methane concentration data, including documentation that the methane was actually supplied to the combustion source. Monitoring and verification is also subject to the following requirements:

1. As part of the consistency application, the project sponsor shall submit a monitoring and verification plan, certified as required at N.J.A.C. 7:27C-10.4(e)8, that includes a quality assurance and quality control program associated with equipment used to determine landfill gas volumetric flow rate and methane concentration. The monitoring and verification plan shall also include provisions for ensuring that me asuring and monitoring equipment is maintained, operated, and calibrated based on manufacturer recommendations, as well as provisions for the retention of maintenance records for audit purposes; and

2. The project sponsor shall annually verify landfill gas methane composition through landfill gas sampling and independent laboratory analysis using applicable EPA laboratory test methods.
