Navigating the RNG Pipeline Permitting Process at BioCycle’s REFOR19

October 15, 2019

BioCycle REFOR19, 19th Annual Conference, Madison, WI

Planning your RNG pipeline design requires a review of how the project might impact land use, archaeologic resources, endangered resources, floodplains, wetlands, and soil erosion. The linear nature of pipeline projects often requires permits from multiple agencies, transportation authorities, and railroads. Getting the agencies involved early and identifying review timeframes will help keep your project on track.

Betsy and Andy will present two case studies for RNG pipeline projects where multiple permitting agencies were involved. Each project presented unique challenges that required additional coordination with local, state and federal agencies as well as the Department of Transportation and railroad operator. They share the obstacles faced and how you can overcome or avoid them to keep your project on schedule.

Maine Residents to Comingle Recycling with Trash and Be More Environmentally Friendly

August 6, 2019

In September the City of Bangor will formally move over to a new arrangement in which residents will throw all of their recycling in with their trash and leave the mixed waste to be picked up from the curbside every week, as now happens with trash.

Bangor will also close their local recycling station as part of the city’s switch to a new integrated waste conversion plant in Hampden developed by Coastal Resources of Maine with Fiberight technology. The new facility includes a materials recovery facility (MRF), organic processing, plastics processing, anaerobic digestion (AD) and wastewater treatment. The integrated technology is intended to increase recycling rates without the need for extensive outreach programs and is easier for customers to use. According to Coastal Resources of Maine, the benefits are:

  • double recycling rates,
  • address global climate and sustainability commitments, and
  • create value from otherwise wasted resources.

The advanced technologies are undergoing final testing at the Hampden, Maine facility, and are already in use at automated material recovery facilities in the United States and in Europe. The end product is cleaner and provides more diverse types of materials that can then be reused to create new products.

The Hampden facility’s advanced MRF has a high degree of separation, recovery, and monetization of commodity products, and then employs additional processes for generating clean cellulose, engineered fuels, and biogas from traditionally non-recyclable materials. Hired for the firm’s technical expertise and experience planning large municipal solid waste and biogas programs and facilities, SCS provided an in-depth examination and analysis of the technologies, program sustainability, and potential economic impacts of the facility.



The facility will serve 116 municipalities and public entities represented by the Municipal Review Committee, a non-profit organization that currently manages the waste disposal activities in Eastern and Northern Maine. The facility is planning to start accepting waste from its municipal customers shortly.

“With the planning and cooperation of many, Fiberight’s providing a truly sustainable solution in Maine while solving several challenges when consumers separate their recyclable materials and eliminating contamination,” stated Bob Gardner, SCS Engineers Senior VP. “The facility is capable of reusing nearly 150,000 tons of what formerly went into a landfill, is processing more municipal solid waste into high-value commodities, and is helping local municipalities and private waste haulers offset the cost of recycling.”

SWANA Alert posted by SCS Engineers: EPA to Hold Public Hearing on the RFS Program Tuesday, August 1

July 31, 2017

Reprinted from SWANA Alert:

On Tuesday, August 1, the U.S. Environmental Protection Agency (EPA) will be holding a public hearing in Washington, DC on the proposed rule, ‘‘Renewable Fuel Standard Program: Standards for 2018 and Biomass-Based Diesel Volume for 2019.’’ In keeping with SWANA’s previous advocacy efforts in regards to the renewable fuel standard (RFS) program, we intend to submit a short written statement to be introduced into the hearing record.

The RFS program is a national policy that requires a certain volume of renewable fuel to replace or reduce the quantity of petroleum-based transportation fuel, heating oil or jet fuel. These amounts are set by EPA each year and the proposed rule will set those levels for 2018. One of the four fuel category amounts that will be set by the RFS is cellulosic biofuels, which includes compressed and liquefied renewable natural gas (RNG) produced from landfill biogas.

As a member of the SWANA Core Advocacy Group, we are notifying you that SWANA intends to submit comments to EPA on the RFS program as part of the August 1st hearing, and in post-hearing comments that EPA will be accepting through August 31st as necessary. These comments will support the testimony of other solid waste industry leaders and ask the EPA set the 2018 RVO standard for cellulosic biofuel at a level that takes into account increased generation of fuel from both existing registered projects and from new projects that will begin generating fuel in 2018. By setting the levels based upon actual current and future capacity instead of on historical data and trends, EPA will ensure that the levels set actually spur demand consistent with increased production. A failure to set the levels high enough would result in a lack of appropriate demand for these fuels, which would undercut the purpose of the RFS program

By setting the levels based upon actual current and future capacity instead of on historical data and trends, EPA will ensure that the levels set actually spur demand consistent with increased production. A failure to set the levels high enough would result in a lack of appropriate demand for these fuels, which would undercut the purpose of the RFS program.

If you or the Chapter or Technical Division members have any questions or concerns about these comments, or if you would like to discuss them further, please contact David Biderman at SWANA.
