35 Years of UST Compliance, How Far Have We Come

35 years ago in 1984, underground storage tanks (USTs) began their official regulated journey. However, the beginnings of the UST regulations began prior to that with concern of inventory loss due to corrosion of the UST system. In the mid-70s, trade associations like the Petroleum Equipment Institute (PEI), Steel Tank Institute (STI) and American Petroleum Institute’s (API) recognized that UST leaks presented a growing problem and began to form study groups to address issue. By 1981, less than 10 percent of all USTs in the ground were protected from corrosion, as estimated by the National Association of Corrosion Engineers (NACE).

Emphasis shifted in the early 1980s from tank regulations for safety reasons (i.e., fire codes) to regulations for protecting the environment and public health. Pressure to deal with the impact of leaking USTs on groundwater grew in 1983 when 60 Minutes aired a segment on leaking USTs. The story focused on gas stations and their leaking USTs that were contaminating a community’s underground aquifer and its water supply.

Shortly after that, President Reagan signed the 1984 Subtitle I RCRA amendments, Solid Waste Disposal Act, providing a comprehensive regulatory program for USTs storing regulated substances including petroleum. There were over two million USTs in 1984. Many of them were bare steel that were potentially corroding and leaking fuel into the ground. Studies, during that time, suggested about 1/3 of UST systems would fail a tightness test and potentially have petroleum releases. In 1985 the Environmental Protection Agency’s (EPA) Office of Underground Storage Tanks (OUST) was created to carry out the mandate to develop and implement a new regulatory program for USTs.

In 1988, EPA published technical requirements for USTs containing petroleum or hazardous substances defined under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980. The technical requirements include leak detection, leak prevention, and corrective action for all USTs containing regulated substances. In 1988, EPA also published financial responsibility requirements for UST owners and operators to demonstrate financial responsibility for taking corrective action, as well as compensating third parties for bodily injury and property damage from releases of tanks containing petroleum. This regulation also included requirements for state program approval.

Also in 1988, “Must for UST” was published. This document informed UST owners about regulations and requirements governing their USTs and covered topics like leak detection, overfill prevention, spill containment, implementation, and the 1998 deadlines.

By December 22, 1998, all active regulated USTs were required to meet the initial 1988 UST performance standards. Many industry experts forecasted that there would be very few ongoing UST releases after this date and states would be able to sunset their UST trust funds in the mid-2000s.

However, UST systems continued to fail which began the first revisions to the UST rules with the UST Compliance Act of 2005 (Energy Act).

On August 8, 2005, President Bush signed the Energy Policy Act of 2005. Title XV, Subtitle B of the act (titled the Underground Storage Tank Compliance Act of 2005) contains amendments to Subtitle I of the Solid Waste Disposal Act, the original legislation that created the UST program.

The UST provisions of the Energy Policy Act focus on preventing releases. Among other things, it expanded eligible uses of the Leaking Underground Storage Tank (LUST) Trust Fund and included provisions regarding inspections, operator training, delivery prohibition, secondary containment, financial responsibility, and cleanup of releases that contain oxygenated fuel additives. While the Energy Policy Act was passed in 2005, the guidelines of the act were not effective until August 8, 2007. Under the guidelines, a state had until August 8, 2009, to develop state-specific requirements consistent with EPA’s guidelines and set implementation by August 8, 2012. Many states elected to implement the requirements in advance of the deadline.

On July 15, 2015, EPA published the 2015 UST regulation and the 2015 state program approval regulation. The revisions strengthened the 1988 federal UST regulations by increasing emphasis on properly operating and maintaining UST equipment to help prevent and detect UST releases. The revisions will also help ensure all USTs in the United States, including those in Indian country, meet the same minimum standards.

The 2015 UST regulation changed certain portions of the 1988 UST technical regulation in 40 CFR part 280. The changes established federal requirements that are similar to key portions of the Energy Policy Act of 2005. In addition, EPA added new operation and maintenance requirements and addressed UST systems deferred in the 1988 UST regulation. Under the regulations, a state had until October 13, 2018, to develop state-specific requirements consistent with EPA’s guidelines and set implementation by October 18, 2021. The implementation of these new rules is varying widely depending on if the state is an EPA state approved program (SPA) or the state’s rule adoption process.

“Must for UST” was updated in 2015 to reflect the new regulations. EPA added new operation and maintenance requirements and addressed UST systems deferred in the 1988 UST regulation. Below is a summary of five key operational changes:

  • Overfill Prevention Equipment Inspections – Overfill protection equipment must be tested and operationally inspected once every three years, and the owner must demonstrate that the equipment operates properly. In addition, owners must inspect automatic shut-off devices, flow restrictors, and alarms.
  • Spill Bucket Testing – Spill prevention equipment must be tested once every three years. The spill bucket must be liquid tight and in proper operational condition.
  • Sumps and Under Dispenser Containment (UDC) Integrity Testing – Once every three years, tank owners must test all sumps used for interstitial monitoring, and the test must show that the equipment is liquid tight using either vacuum, pressure, or liquid testing methods. If you have double-walled sumps and/or automatic alarm shut-off sensors, your requirements may be different.
  • Sumps, UDC and Release Detection Equipment Inspection Visual – Once a year, tank owners must visually check the sumps for damage, releases, and leaks. Also, probes and sensor tests must be conducted annually to ensure they are in operational condition.
  • Monthly Spill Bucket and Release Detection Walk Through Inspections – Every 30 days, tank owners must conduct monthly UST system walkthrough inspections for spill buckets, fill caps, release detection equipment, alarm conditions, check/remove obstructions in fill pipe, and check interstice of double-walled spill buckets (if present).
  • Compatibility Determination – Owners and operators must use UST systems made of or lined with materials that are compatible with the substance stored in the UST system. Owners and operators notify the implementing agency at least 30 days prior to switching to a regulated substance containing greater than 10 percent ethanol, greater than 20 percent biodiesel.

After years on the periphery of American political life, climate change is having a bit of a moment. Activists (along with five Democratic presidential candidates and at least 100 members of Congress) have rallied behind a Green New Deal that proposes a crash program to decarbonize the US economy. Polls on climate change show rising rates of concern across the country and among both political parties. It seems that after decades near the bottom of Democratic priority list, climate has broken into the top two or three.

Now proposals are being made to significantly change the use of petroleum for transportation. The Green New Deal (GND) aims to address climate change and economic inequality. The initial draft proposes that the United States (US) archives net-zero emissions by 2030.

In one GND – FAQ that was given to National Public Radio, one of the highlighted projects was to “totally overhaul transportation by massively expanding electric vehicle manufacturing, build charging stations everywhere, build out high-speed rail at a scale where air travel stops becoming necessary, create affordable public transit available to all, with goal to replace every combustion-engine vehicle.”

Michael Bloomberg has founded Beyond Carbon, an effort that he described as a “grassroots effort to begin moving America as quickly as possible away from oil and gas and toward a 100 percent clean energy economy.”

Today there are around 500,000 USTs operating at 200,000 sites. Significant Operational Compliance is at 70% and there are approximately 65,000 sites left to be cleaned up. Since 1984, almost 2,000,000 USTs have been closed and 500,000 sites cleaned up.

The U.S. EPA’s UST program has made significant contributions to protect the environment during the last 35 years. One of the main reasons for the program’s success is the involvement of everyone in the process from states, territories, tribes, industry, owners/operators, service providers, equipment manufacturers, and trade associations have worked together from the beginning and continue to work together today. As we are in the middle of implementing the next set of UST requirements, I am confident we will continue to see improvement in compliance, reduction in the number of releases, and improved responses to potential releases.

EPA Enforcement Annual Results for Fiscal Year 2018

The US Environmental Protection Agency (EPA) recently released its annual enforcement results for the 2018 fiscal year (ranging from October 1, 2017, to September 30, 2018). The report highlights the results of the agency’s civil and criminal enforcement over the past year. Susan Bodine, the Assistant Administrator for OECA, summarizes EPA’s enforcement priorities, explaining “In fiscal year 2018, we continued our focus on expediting site cleanup, deterring noncompliance, and returning facilities to compliance with the law, while respecting the cooperative federalism structure of our nation’s environmental laws.”

Highlights from the 2018 report include:

  • EPA assessed approximately $69.5 million dollars in administrative and civil judicial penalties in FY 2018. The report notes that it typically takes 2.25 years to move civil cases referred by EPA to the Department of Justice resolved via settlement or to proceed towards litigation with the filing of a complaint.
  • In FY 2018 over 1,560 facilities voluntarily disclosed violations pursuant to EPA’s self-disclosure policies. This represents a 47% increase in self-disclosures from FY 2017 and an even greater climb from earlier years (for example, there were only 666 facilities that self-disclosed in FY 2015). EPA attributes the increases in the self-disclosure of environmental compliance issues to increased use of the eDisclosure reporting that was launched two years ago and EPA’s introduction of the New Owner Audit Policy this past fiscal year.
  • EPA reported $88 million in criminal fines, restitution and court ordered environmental projects. The fines and restitution imposed in FY 2018, however, were higher than at any point in the 2008 to 2012 period. The data also shows that EPA continues to pursue criminal enforcement cases.
  • EPA conducted about 10,600 inspections and compliance evaluations in FY 2018. Although this represents about a 10% decline from the prior year, it is consistent with a nearly decade-long continuing decline in EPA inspections and evaluations. Part of the decline, as reported by EPA in its annual report, is attributable to increased reliance on data analytics and other tools to improve inspection targeting.
  • EPA reported that private parties committed to spend roughly $453 million to cleanup new sites. Despite the agency’s stated focus on increasing Superfund enforcement, this amount is less than half of FY 2017’s approximately $1.26 billion total. However, a couple of significant cleanup cases can heavily impacted the annual totals.

The full report of EPA’s 2018 enforcement and compliance assurance accomplishments is available here, https://epa.maps.arcgis.com/apps/Cascade/index.html?appid=0b9d73f351d648698f63bba3f3b15114, EPA’s FY18 Enforcement Annual Results Data Graphics are available here, https://www.epa.gov/sites/production/files/2019-02/documents/fy18-enforcement-annual-results-data-graphs.pdf and EPA’s News release for the 2018 Annual Environmental Enforcement Results can be found here, https://www.epa.gov/newsreleases/epa-announces-2018-annual-environmental-enforcement-results.

PPM Celebrates 25 Years

This month PPM Consultants is celebrating our 25th anniversary in business. The celebration will continue throughout the year in appreciation of our wonderful clients and exceptional team. The company will also celebrate its silver anniversary during its annual PPM Roadshow in February, where the firm’s principals will meet with PPM staff to share their vision for the upcoming year, as well as reflect on the previous year’s successes. Founding principals Todd Perry, Keith Pyron and Michael McCown agree they will be reflecting on 2018 proudly. Perry said, “2018 was a truly special year, with incredible record breaking growth across all measurable indices. These accomplishments would not be possible without our fantastic clients and outstanding team.”

PPM was founded on January 17, 1994, to provide environmental consulting services to the petroleum marketing industry, with a primary focus on soil and groundwater contamination assessment and remediation. The company began operations with a five-person office in Monroe, LA and a one-person office in Mobile, AL. Since then, the firm has seen both geographic and revenue growth, and has diversified its environmental offerings to include air, water and waste permitting and reporting, due diligence and other services to the manufacturing, energy, commercial and government sectors. The focus of the firm, both then and now, is to provide common sense, cost-effective environmental solutions to clients, who depend on PPM for honest answers to complex problems.

McCown states, “We’ve seen our finest year ever by focusing on our clients’ needs.” McCown is quick to acknowledge that meeting client goals on a daily basis is the only way that company milestones like reaching $27 million in revenues and growing offices have been possible. With this approach, PPM has grown to seven offices across the Southeast with a staff of over 100. Since its founding, PPM has earned repeated placement on the Inc. 500, the ENR Environmental 200, and the Zweig-White Hot Firm lists for being one of the fastest-growing environmental firms in the nation.

PPM looks to 2019 with goals to exceed $30 million in revenue, extend its service area and acquire firms whose services will provided expanded geographic coverage and synergy with PPM’s existing offerings.

The PPM team looks forward to many more great years ahead. Pyron adds, “It has been a truly great and satisfying experience to have been in business the last 25 years with our team.”

A Year-End Review of EPA’s Recent Air Permitting Guidance Changes

As we enter into 2019, it is important to reflect on the air permitting guidance changes we have seen in what has been a very active year in EPA air permitting guidance. These guidance changes, especially those under the complex NSR review process, will impact the air permitting process for capital projects going forward. Below is just a brief summary of some of the major EPA actions affecting the air permitting process in 2018:

Once In, Always In Policy

Withdrawal of the “Once In, Always In” policy was published on January 25, 2018. This memorandum reverses a long-standing policy that EPA has held since 1995 that a source subject to major source standards for Hazardous Air Pollutants (HAP) would always remain subject to those standards, even if it subsequently reduces its emissions below the major source threshold. (Link)

Project Emissions Accounting

Changes to the NSR “Netting” process were published on March 13, 2018. This memorandum establishes the concept of “Project Emissions Accounting,” and allows a facility subject to NSR review to consider both emissions increases and decreases in the first step of the NSR review process, rather than just increases. (Link)


President Trump issued a memo to EPA on April 12, 2018, which was followed by the EPA “Back-to-Basics” memorandum on May 9, 2018. Both of these memoranda address the National Ambient Air Quality Standards (NAAQS) review process and aim to make the process more transparent, and stress that attainment determinations be made in a timely manner. (Link 1, Link 2)

Source Aggregation

EPA clarified source aggregation and the definition of “Common Control” in a letter to the Pennsylvania Department of Environmental Protection on April 30, 2018 regarding Meadowbrook Energy, LLC. Further refinements to source aggregation policy were included in an October 16, 2018 letter from EPA to the Wisconsin Department of Natural Resources regarding the Janesville City Landfill. Both letters stress that common control is not merely the ability to influence another facility, but the power to direct activities which would directly impact air emissions and compliance obligations. (Link 1, Link 2)

Draft guidance on source aggregation and adjacency in NSR review was published on September 4, 2018. This guidance stresses that functional interrelatedness should not enter into a decision on whether or not two sources are “adjacent,” and that adjacent means physical proximity only. This guidance does not, however, include a physical distance threshold for adjacency, as is used in the industry-specific oil and gas adjacency criteria (one quarter mile). (Link)

ACE Rule

On August 21, 2018, EPA proposed the Affordable Clean Energy Rule as a replacement to the 2015 Clean Power Plan. This rule establishes emissions guidelines for states to develop plans to address Greenhouse Gas (GHG) emissions from coal-fired power plants. (Link)

Ambient Air

On November 9, 2018, EPA published draft guidance on the definition of “ambient air.” If finalized, this guidance would allow ambient air analyses to exclude areas that are inaccessible due to reasons other than just fencing or physical barriers. Public comment on this draft guidance is open through December 21, 2018. (Link)

Project Aggregation

On November 15, 2018, EPA published a reconsideration of an earlier action in 2009 that clarifies what is considered a “project” under New Source Review (NSR) and when projects should be aggregated together during an NSR analysis. This action affects how facilities going through Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) characterize their projects when determining whether they constitute a “major modification.” While there will still be some case-by-case element to what constitutes a “project,” this action gives regulated entities as well as regulators criteria to help make a judgment on whether certain changes at a facility should be aggregated in an NSR analysis. (Link)

With all the movement we saw in 2018, we can expect 2019 to be another active year. PPM will continue to stay up-to-date on the latest regulatory developments and summarize their impact on the regulated community.

If this summary has sparked your interest in a certain area, please feel free to reach out to ned.coleman@ppmco.com for a collaborative discussion regarding your facility.

Deregulation Trends in the Wake of “In-One-Two-Out” Policy

On January 30, 2017, the day President Donald Trump took office, one of his first measures was to sign in Executive Order 13771.1 This executive order became known as the “In-One-Two-Out” policy whereby for every new regulation adopted, two regulations should be cut so as to not increase the incremental costs of new regulations.  It has been almost two years since this executive order was signed and there are two significant trends already showing.



  1. The total number of regulations has decreased

Figure 1 below shows the total number of pages in the federal register by year.2 In 2017, there was a significant reduction of 35% in the total number of pages in the Federal Register. The last time there was fewer pages of regulations was in 1993, 25 years ago.

[1] “Reg Stats | Regulatory Studies Center | The George Washington University”. Regulatorystudies.Columbian.Gwu.Edu, 2018, https://regulatorystudies.columbian.gwu.edu/reg-stats. Accessed 30 Oct 2018.

  1. The rate of new significant regulations has substantially slowed

Not only has the total number of regulations decreased, but also the rate at which new regulations being published has dramatically decreased. Figures 2 and 3 show a step decline in significant new regulations, where “significant regulatory action” means any regulatory action that may have an annual effect on the economy of $100 million or more.3,4 This trend equates to an 81% reduction in new significant regulations between 2016 and 2017.

Key Take-Aways

The data over the past year and a half shows that the pace of regulations has slowed, which promotes a stable regulatory climate (i.e. not a lot of new projected regulations). This reduced regulatory expansion period may lead companies to consider:

  • New projects or expansions
  • Debottlenecking projects
  • Asset Acquisitions or Divestitures
  • Other various permit modifications or amendments

If your company is in a capitol deployment mode and needs additional support in regards to environmental permitting and/or plans for your projects, be it manpower or technical expertise, PPM Consultants can assist in your environmental needs.

Upcoming Compliance Dates for Refinery Sector Rule 40 CFR 63 CC

Compliance Date and Summary of Requirements

January 30, 2019, is rapidly approaching, and for those facilities with flares subject to the requirements in Subpart CC, that’s your compliance deadline for completing a Flare Management Plan (FMP). Flares that are subject to the requirements in §63.670 are also subject to the flare monitoring requirements in §63.671, which include developing a monitoring plan, operating a continuous parametric monitoring system (CPMS), and submitting periodic reports.

Many of the facilities subject to Subpart CC were already required to develop FMPs under 40 CFR Part 60 Ja; however, the additions to Subpart CC necessitate updates to the existing plans to ensure both regulations are met. Whereas Ja focused on minimizing overall flare volumes and emissions of pollutants such as sulfur dioxide (SO2), Subpart CC addresses minimizing hazardous air pollutant (HAP) emissions by placing enhanced monitoring and operational requirements on flare combustion such as:

  • Continuous operation of a pilot flame
  • Operation without visible emissions (VE)
  • Maximum flare tip velocity
  • Minimum combustion zone heat content (>270 Btu/scf) and proper steam or air assistance

In addition to the monitoring and operational requirements, facilities subject to Subpart CC must develop a CPMS monitoring plan that details quality control/quality assurance (QA/QC) requirements and procedures including, but not limited to:

  • Identification of the specific flare being monitored and flare type
  • Parameters monitored and type for each flare
  • Description of the monitoring equipment
  • Description of the data collection and reduction systems, including algorithms used to demonstrate compliance
  • Routine QA/QC procedures with descriptions for calibrations, calibration drift, spare parts inventory, etc.

Additionally, facilities should use this time to conduct a thorough review of their FMPs and other monitoring plans to verify the plans are accurate and reflect the existing design and operation. Changes to existing flare minimization plans/strategies along with addressing modifications to the facility’s baseline or developing alternatives baselines should also be discussed during this time. This is also a good time for a facility to review its fence line monitoring program, which was first required to be implemented on January 30, 2018, since it will be coming up on a full years’ worth of data to analyze.

PPM has professionals with flare management plan experience who would be happy to discuss these required updates. Please give us a call at (251) 990-90000 if you need help or have any questions. Feel free to reach us by email: Isaac Smith (isaac.smith@ppmco.com), Ned Coleman (ned.coleman@ppmco.com).
