With major source limits in the Denver metro area non-attainment area lowering to 25 tons per year of NOx or VOC in early 2022, many sources that have previously considered themselves to be small may be bumping into major source limits and the permitting requirements applicable to major sources. The 25 tons per year emission level is based on a facility’s Potential to Emit (PTE). A PTE inventory shows the maximum amount of emissions that COULD come from your facility if it were running at maximum capacity all the time, even if your facility would never run consistently at that level.
Does your facility have a Potential to Emit (PTE) Inventory? If you have some sources that are controlled, you may or may not be able to count that control in your PTE Inventory, depending on your permits. Maybe your facility only has a few sources that require a permit and the emissions from those sources added together are less than 25 tpy of NOx or VOC, but did you include your insignificant sources, such as gas-fired heaters, fire pumps, emergency generators, and small fuel tanks, in your PTE? If you would like to discuss your facility’s PTE inventory, Applewood can help!
The Air Pollution Control Division (APCD) is working on a Greenhouse Gas (GHG) Audit Program that will focus on reducing GHG emissions from manufacturing facilities. The program has been created in response to Colorado Revised Statute Section 25-7-102(2(g) which set the following goals for GHG reduction in the state:
The audit program will be based on manufacturing facilities’ relative contribution, so large contributors to GHG emissions will be the focus of the program in the beginning. Manufacturing facilities with direct emissions of equal to or more than 50,000 metric tons of CO2e per year through 2019 will be the affected facilities at first. It is expected that the applicability will be lowered to smaller contributors in the future. Facilities that will be excluded will be Oil and Gas, Landfills, Underground Coal Mines, Electric Generating Units and Food Processing Facilities. Most of those types of sources are covered under separate regulations.
The audit program will require energy and emission control audits addressing GHG emissions from energy-intensive, trade exposed manufacturing facilities (EITEs) as well as non EITE facilities. For EITEs it will require that the audit be done by a 3rd party every 5 years through 2035. Non EITE facilities will be required to implement management systems for energy and GHG emission reductions over a 5-year period. APCD wants facilities to help decide what sources should be included in their own audit, with the focus being on the sources that have the most emissions.
The audit will help to establish GHG Best Available Control Technologies (BACT) and Best Available Energy Efficiency Practices (BAEEP). These will likely be set per facility instead of per industry. The audit report should recommend a compliance process. If sources do not meet GHG BACT and BAEEP, the commission will consider the regulatory requirements to further mitigate the costs of reducing emissions and provide incentives to reduce emissions. APCD would also like to utilize existing programs like ISO.
APCD expects to have draft language for the audit program out by mid-February 2021. In April there will be a request for a rulemaking and a rulemaking hearing in July. For more information on the upcoming GHG audit program for Colorado manufacturer’s, go to the CDPHE website for the program:
On October 22, 2020 the EPA finalized the latest guidance on Project Emissions Accounting for Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR). In short, the new guidance says that sources can consider emissions reductions in the first step of emissions accounting, which allows them to couple emissions reductions with increases that may be necessary for their process. These reductions can help sources avoid a more complicated permitting process.
It is, however, up to some individual states to decide if they want to follow this guidance. States can decide to use the old guidelines which do not allow for subtraction of emissions reductions in the first step of the process.
For more details on this final action on Project Emissions Accounting, the EPA has a fact sheet and a link to the final rule posted here: https://www.epa.gov/nsr/nsr-regulatory-actions
Industry and citizens in Colorado are holding their breath for major changes that will be happening in our state in the upcoming months. The Denver metro region is a non-attainment area for ozone. This means that our air quality is worse than the National Ambient Air Quality Standards for Ozone. Ozone precursors are VOC and NOx. Currently Sources that emit over 100 tons per year of VOC and NOx need to have Title V permits. However, this will soon change. The change is expected in the second half of 2019 or early 2020. Current sources that have air permits with VOC or NOx emissions between 50 and 100 tons per year are going to have to either limit their emissions to less than 50 tons per year or apply for a Title V permit within 1 year of the serious designation. If a source intends to submit a synthetic minor permit, which would limit their emissions to less than 50 tons per year, then the permit needs to be ISSUED by the Air Pollution Control Division within the 12-month period after the change to avoid Title V permit application requirements. In some cases, the revised permit will need to be issued before July 1, 2020 to avoid additional RACT analysis. Often permits take several months to be issued by the Air Pollution Control Division, so applications for synthetic minor permits need to be submitted in the upcoming months.
Colorado also passed Senate Bill 181 which calls for a reorganization of the Colorado Oil and Gas Conservation Commission and to prioritize their mission on the protection of Public Safety, Health and Welfare, the Environment, while also requiring additional regulation from the Air Quality Control Commission for the oil and gas sector and transmission sector. These changes will likely take years to complete.
Additional legislation was passed including HB 19-1261 which calls for a Climate Action Plan to Reduce Pollution and SB19-96 which aims to Collect Long-Term Climate Change Data. This legislation also establishes sweeping air emissions and environmental rulemakings and changes in the coming years and decades.
At Applewood Environmental, our mission is to stay on top of these regulatory changes and guide our clients through them to remain in compliance and also give their businesses the ability to grow.
