Revisions to the Greenhouse Gas Reporting Rule Increase Reporting Requirements for Landfills

EPA recently made amendments to 40 CFR Part 98, the Greenhouse Gas Reporting Rule. These changes may have major implications on emissions calculations and reporting across all sectors, including municipal solid waste (MSW) landfills (Subpart HH) and industrial landfills (Subpart TT). A pre-publication copy of the amendments was made public on November 15, 2013, and may be downloaded from the following link, along with fact sheets and additional information:

http://www.epa.gov/ghgreporting/documents/pdf/2013/documents/2013-data-elements.pdf.

This final rule is effective on January 1, 2014.

The most significant change impacts the likelihood of pollutant emissions to exceed reporting thresholds. A total of 23 global warming potential (GWP) values (100-year time horizon) have been revised in Table A-1 to Subpart A of the Rule. These values are used to convert calculated GHG emissions to carbon dioxide equivalent (CO2e) values, which are then compared to the reporting threshold of 25,000 CO2e. The most notable change affecting Subparts HH and TT is to the GWP for methane, which is increased from 21 to 25. The impact is felt by landfills that were previously below the reporting threshold.  Under the old GWP of 21, landfills that generated 1,190 metric tonnes of methane would not be required to report.  Now, with the new methane GWP of 25, landfills generating 1,000 metric tonnes of methane would be subject to the reporting rule.

In response to comments, landfills and other facilities that were beneath the reporting threshold for reporting year 2012 but now exceed the reporting threshold due only to the increase in GWP are not required to report 2013 emissions. For landfills specifically, the following conditions are in place for this exemption to apply:

1. No waste was accepted on or after January 1, 2013;
2. The landfill generated less than 1,190 tonnes of methane in 2013; and
3. The landfill was not required to report in any reporting year prior to 2013.

Landfills not meeting the above exemption that are newly subject to reporting as a result of the changes to GWP values are required to begin collecting data on January 1, 2014 for the 2014 reporting year. These reporters are required to submit their first reports, covering the 2014 reporting year, by March 31, 2015.

Additional changes are made to several factors used in calculating GHG emissions, including Degradable Organic Carbon (DOC) and density of methane. Data collection frequency requirements have also been relaxed from weekly to monthly for methane and other parameters.

Impacts of Oil and Gas Industry in North Carolina Evaluated by Funding Study Group

In an effort to identify potential sources of funding to address impacts from anticipated oil and gas exploration and recovery, the Mining and Energy Commission (MEC) issued the final report of the Funding Levels and Potential Funding Sources Study Group.  The study, sanctioned under Section 2.(j) of Session Law 2012-143 was prepared by the MEC in conjunction with the Department of Environment and Natural Resources (DENR), the DOT, the NC League of Municipalities, and the NC Association of County Commissioners.

Impacts addressed in the report include repair of roads damaged by heavy truck and equipment; and remediation and reclamation of drilling sites abandoned by responsible parties, among other issues as determined by the MEC.  Costs borne by DENR and DOT to administer environmental and overweight vehicle permits are presented.  Costs to remediate environmental impacts (e.g., groundwater and surface water) are not included in this study.  Evaluated cost recovery and financial assurance mechanisms include permit and impact fees charged to the permittee/project owner, taxes, and bonds.  State and local costs projected in this report are limited to the 14 North Carolina counties located in the Triassic Basin.

Excise and severance taxes and bonding measures implemented by other States with active oil and gas extraction industries were considered, as were industry costs for activities such as well abandonment.  Bonding is recommended for activities such as geophysical exploration, well plugging/abandonment, and site reclamation (i.e., haul roads, pits, pads, and stockpiles).

Regarding damages to water supply, personal property, and marketable surface resources (e.g., timber, cropland), the report findings are limited to the study group determination that “some level of protection for affected land owners… shall be addressed in lease negotiations.”

The report, along with legislative proposals, is due for submittal to the Joint Legislative Commission on Energy Policy and the Environmental Review Commission by October 1, 2013.  The report and commission activities can be viewed at the following web address:

Proposed Changes to North Carolina Toxic Air Pollutant Rules

A hearing is scheduled for September 19, 2013 at 3:00pm to discuss proposed changes to North Carolina air toxics contained in Session Law 2012-91, signed into law June 28, 2012.  Proposed changes include exemption from state air toxics rules for major sources of air pollution subject to federal Maximum Achievable Control Technology (MACT) or area sources subject to General Achievable Control Technology (GACT) rules.  For instance, MSW landfills subject to 40 CFR Part 63 Subparts AAAA or ZZZZ, or Part 60 Subpart JJJJ may not be required to determine ambient air levels of toxic pollutants from landfill or flare emissions.

Additional proposed changes include:

Exemption of certain natural gas and propane fired combustion sources and certain emergency generators;

  • Clarification of the term “actual rate of emissions”;
  • Removal of the term “unadulterated wood”;
  • Repeal of air toxics rules for wastewater treatment systems at pulp and paper mills; and
  • Relaxation of toxic emission rates requiring a permit and acceptable ambient air levels (AAL) for arsenic and asbestos.

The hearing will be held in the Training Room (Room 1210) in the Green Square office building, 217 West Jones St., Raleigh.

More information may on the public hearing may be downloaded here.

S+G Becomes Charter Member of the Institute for Sustainable Infrastructure

Smith Gardner, Inc. (S+G) is pleased to announce it has become a charter member of the Institute for Sustainable Infrastructure (ISI), whose goal it is to change the way infrastructure is conceived of, designed, constructed and operated to better meet the challenges of our resource-constrained world. Taking a more visible stance regarding sustainability is a natural step for the firm, which has for the past decade been instrumental in reducing greenhouse gas emissions by providing consulting services for numerous landfill-gas-to-energy and landfill gas collection projects throughout the southeastern United States. Charter membership in ISI is a milestone indicating the completion of many behind the scenes moves to equip the firm to incorporate sustainability principles into its core services and to add new sustainability-driven services, such as expanded composting consulting services and enabling owners to achieve project recognition through the Envision rating system, as explained later in this article.

Sustainability is not a separate service line for S+G, it is the pathway to providing better value to our clients through expanding the conceptual space within which we provide our core services. We will be able to achieve greater value over the life of a project or facility by applying longer planning horizons and multi-disciplinary approaches. Our clients may not even realize that innovative solutions to their problems have grown out of the multidisciplinary studies our professionals engage in.

The firm’s involvement with ISI is spearheaded by Thomas Maier, who has earned the Envision™ sustainability professional (ENV SP) credential recognizing his demonstrated ability to apply sustainability principles to infrastructure projects, and to use the recently debuted Envision™ sustainable infrastructure rating system. Mr. Maier was also a member of the first graduating class of ISI Verifiers who are qualified to rate projects on the basis of documentation submitted by the design team. The Envision™ rating system raises the bar on infrastructure performance by recognizing efforts that restore ecosystems as well as evaluating infrastructure throughout its full lifecycle from planning through decommissioning. Through his work with the Economics Committee of ISI, Mr. Maier is working with economists and engineers to develop an enhancement to the Envision™ rating system that enables the monetary equivalent of environmental and cultural benefits to be rationally quantified, thus providing an economic driver for projects to achieve higher levels of sustainable performance. Mr. Maier has also earned the designation of LEED AP BD+C from the Green Building Certification Institute, recognizing his proficiency in applying the LEED rating system to building design and construction.

Jorge Montezuma is leading the firm’s expanding composting services line, which includes consulting and design services for food waste collection and composting, vermicomposting, and agricultural byproduct composting. Mr. Montezuma has recently been elected the Secretary of the North Carolina Composting Council.

10-Year Landfill Permit Rule Comments Due

On January 2, 2013, the North Carolina Register published proposed rule changes to 15 NCAC 13B.0206, Option to apply for issuance of 10-year permit for sanitary landfill or transfer station (NC Register Volume 27, Issue 13, Page 1272).  The proposed changes provide an option of extending the permitting terms for the design, construction, and operating phase of a sanitary landfill from five years to ten years.  However, the ten year permit holder will be subject to a five year design phase review.  The proposed rule change is as follows:

(a) An applicant for a sanitary landfill or transfer station permit subject to Section .0400, .0500 or .1600 of these Rules may apply for a permit for a design, construction and operation phase of five years or a design, construction and operation phase of ten years. A permit for a ten-year phase of construction and operation of a sanitary landfill shall meet the five-year phase requirements contained in Section .0500 and .1600, applied in two five-year increments.

(b) A permit issued for a designed phase of ten years shall be subject to review within five years of the issuance date, as provided in Rule .0201(g). Permit modifications issued for a ten-year phase of construction or operation of a sanitary landfill or transfer station shall be made in accordance with rules in effect at the time of review and include an updated operations plan for the facility, revisions to the closure and post-closure plans and costs, and updates to the environmental monitoring plans.

As stated in the published rules, “the Division of Waste Management seeks to change rules related to the duration of sanitary landfill or transfer station permits to comply with recent changes in state law. The current rule and statutory requirements are based on five-year permit durations. The proposed rule change is necessary to comply with new state laws and is in the public interest because it provides the regulated community with opportunities for cost savings and greater permit length flexibility.”

This proposed rule was one of the regulatory reform recommendations developed during the 2012 short session that focused on reducing the permitting burden on regulated entities.   Furthermore, Senate Bill 810-Regulatory Reform Act of 2012 (S.L. 2012-187) directed the North Carolina Department of Environment and Natural Resources (DENR) to track the processing time for permits issued by the One-Stop, Express Permit, and Certification Review programs.  In addition to evaluating these permitting processes, DENR must complete a comprehensive review of  each of their permit, license, and approval programs; identify which program should be subject to a similar permit process tracking system; and report their findings from this review to the Environmental Review Commission before January 15, 2013.

Parties interested in submitting written objections to the agency regarding the proposed changes should contact:

Stormwater Permit

The current NPDES General Permit NCG120000 (Permit) for landfills will expire on October 31, 2012. A draft Permit for public comment has been published here. The comment period ends on October, 4 2012 with the new Permit set to issue on October 19, 2012 (Effective November 1, 2012). The following is a summary of the major differences between this draft Permit and the current Permit set to expire.

1.0 MONITORING PARAMETERS

Qualifying discharges from vehicle maintenance areas will now include analytical monitoring for Total Petroleum Hydrocarbons (TPH) instead of the previous Oil & Grease analysis. This is based on the assessment that TPH is more specific for petroleum hydrocarbons than Oil & Grease. There should be no cost difference between these analyses.

Total Suspended Solids (TSS) is a parameter monitored in the current Permit; however, lower TSS thresholds have been implemented for discharges in certain water designations (ORW, HQW, trout, and primary nursery area (PNA) waters). Benchmark values are discussed below.

No other change is proposed for monitoring parameters.

2.0 MEASUREABLE STORM EVENT

The draft Permit introduces an updated definition of what storm event should be sampled. The term “representative storm event” has been replaced by “measurable storm event.” The “measurable storm event” is an event that results in an actual discharge, rather than an event with a rainfall measuring 0.1 inches or more. To qualify as a measurable storm event, previous storms must have been at least 72 hours prior. Samples must be collected within the first 30 minutes of discharge.

3.0 ADVERSE WEATHER

The draft Permit defines adverse weather conditions and allows the permittee to forgo sampling if conditions are dangerous or inaccessible. These events must be documented and included with records.

4.0 QUALITATIVE MONITORING 

Qualitative monitoring schedules have not changed but the following requirements have been modified to include an implementation schedule for corrective actions:

  • “Qualitative monitoring shall be conducted at least once every seven calendar days, and within 24 hours after any storm event of greater than 0.5 inches of rain per 24 hour period. During stormy periods, and whenever runoff occurs daily, all stormwater controls shall be inspected daily and immediately before closing operations for the weekends or holidays.”
  •  “In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall document the suspected cause of the condition and shall document corrective actions taken in response to the discovery. Uncontrolled releases of mud or muddy water, or visible sedimentation found off site, shall be recorded with a brief explanation as to the measures taken to prevent future releases as well as any sediment clean‐up measures taken.”
  • “If the permittee’s qualitative monitoring documentation indicates that existing stormwater controls are ineffective, or that significant stormwater contamination is a recurring condition, the permittee shall investigate potential causes, evaluate the feasibility of corrective actions, and implement feasible corrective actions within 60 days. A written record of the permittee’s investigation, evaluation, and response actions shall be kept on site.”
  • “The permittee shall record the required qualitative monitoring observations on the SDO Qualitative Monitoring Report form provided by the Division and shall retain the completed forms on site. Qualitative monitoring results should not be submitted to the Division, except upon DWQ’s specific requirement to do so.”

5.0 ANALYTICAL BENCHMARK VALUES

Benchmark Values for Analytical Monitoring Requirements

Discharge Characteristics Benchmark Value
Chemical Oxygen Demand 120 mg/l
Fecal Coliform 1000 colonies per 100 ml
Total Suspended Solids (TSS) 100 mg/l
TSS (ORW, HQW, Trout, and PNA) waters 50 mg/L

Benchmark Values for On-Site Vehicle and Equipment Maintenance Activities

Discharge Characteristics Benchmark Value
pH Within the range 6.0 ‐ 9.0
Non‐Polar Oil & Grease/TPH [EPA Method 1664 (SGT‐HEM)] 15 mg/l
Total Suspended Solids (TSS) 100 mg/l
TSS (ORW, HQW, Trout, and PNA waters) 50 mg/L

6.0 TIER THREE RESPONSE ACTIONS

The Tier Three response actions that have been added to the draft Permit are summarized below:

“During the term of this permit, if the valid sampling results required for the permit monitoring periods exceed the benchmark value for any specific parameter at any specific outfall on four occasions, the permittee shall notify the DWQ Regional Office Surface Water Supervisor in writing within 30 days of receipt of the fourth analytical results. DWQ may, but is not limited to:

  • Require that the permittee revise, increase, or decrease the monitoring frequency for some or all parameters;
  • Rescind coverage under the General Permit, and require that the permittee apply for an individual stormwater discharge permit;
  • Require the permittee to install structural stormwater controls;
  • Require the permittee to implement other stormwater control measures;
  • Require the permittee to perform upstream and downstream monitoring to characterize impacts on receiving waters.”

7.0 DUTY TO COMPLY (FINES)
The Clean Water Act fines have increased in Part III, Section A, 2 (a) and (f) of the draft permit.

8.0 CLOSING

Several important changes are being proposed for stormwater monitoring that may impact your landfill operation in the future. Smith Gardner, Inc. would be glad to discuss this draft Permit or other NPDES permits with you if you have any questions. More information and the address for comments may be found here: http://portal.ncdenr.org/web/wq/ws/su/current-notices/-/journal_content/56_INSTANCE_y9Oq/38364/8522326
