Duane Tilden‘s insight:

The regulation requires that municipal solid waste landfills with 100,000 tonnes or more of waste in place or with an annual waste acceptance rate exceeding 10,000 tonnes to undertake an assessment of landfill gas generation and to submit the results to the Ministry in a report by January 1, 2011.  […]

If according to Landfill Gas Generation Assessment Procedure a regulated landfill site is estimated to generate 1000 tonnes or more of methane, the owner or operator of that site is required to complete a LFG management facilities design plan and to install the designed facilities at the landfill site.  The Landfill Gas Management Facilities Design Guidelines (PDF/9.3 MB)  […]  The performance standards prescribed in the document are intended to implement high-efficiency LFG collection systems. This Guideline must be used by landfill owners, operators, and qualified professionals in the preparation of LFG facilities design in accordance with the Landfill Gas Management Regulation.

U.S. EPA’s addition of oil, gas and coal methane emissions to its online greenhouse gas tracking tool revealed an 82.6-million-metric-ton increase in carbon dioxide equivalents over numbers from the previous year, when those figures were not…

Duane Tilden‘s insight:

Coal power still dominates emissions

Last year, EPA completed standards requiring hydraulically fractured gas wells to use technology that will cut toxic emissions and smog-forming pollution by 2015.

As a co-benefit, the upgrades will also reduce methane by up to 1.7 million tons, said EPA. However, environmental groups have said that the methane issue must be addressed separately from other pollutants (ClimateWire, April 19, 2012).

Coal-fired power plants are the largest source of carbon emissions, outpacing the second-largest source — petroleum and natural gas systems — by a factor of almost 10-to-1. Power plants accounted for two-thirds of total greenhouse gas emissions.

Fracking Seen by EPA as No. 2 Emitter of Greenhouse Gases

Natural gas and oil production is the second-biggest source of U.S. greenhouse gases, the government said, emboldening environmentalists who say tighter measures are needed to curb the emissions from hydraulic fracturing.

Duane Tilden‘s insight:

[…] the U.S. Environmental Protection Agency for the first time included oil and natural- gas production. Emissions from drilling, including fracking, and leaks from transmission pipes totaled 225 million metric tons of carbon-dioxide equivalents during 2011, second only to power plants, which emitted about 10 times that amount.

The EPA report on oil and gas looked at emissions from basins, or large production areas, not individual wells. Among the top emitters were ConocoPhillips’ operations in the San Juan basin in New Mexico, and Apache Corp.’s operations in the Permian basin in Texas. Both companies are based in Houston.
