The Fate of the Coal Ash Management Commission

March 19, 2016. An earlier post discussed the N.C. Supreme Court decision in McCrory v. Berger. In brief, the court ruled that laws giving the General Assembly  power to appoint a majority of the members of the Coal Ash Management Commission (CAMC) and two other state commissions violated the N.C. Constitution’s provisions on separation of powers.  (See the earlier post for more detail and a link to the court’s opinion.)   The decision means the Coal Ash Management Commission cannot take any further action until the General Assembly amends the CAMC’s  appointment statute  to be consistent with the court’s decision and new appointments are made.  The most likely solution would be to give the Governor power to appoint a majority of the members;  the law could be amended as early as April of this year when the legislature convenes again.

Multiple news outlets have now reported that the McCrory administration has taken steps to effectively disband the Coal Ash Management Commission in advance of the April legislative session.  The Charlotte Observer’s Bruce Henderson reported that the Governor’s Office informed CAMC executive director  Natalie Birdwell  that the commission is “no longer a legal entity”.  The same Charlotte Observer article reports that the move by the Governor’s Office to shut down the commission’s work will dissolve contracts with independent experts retained by the commission to provide an outside review of  the Department of Environmental Quality’s (DEQ) proposed risk classification of coal ash ponds.

A few observations about the Governor’s decision to shut down the Coal Ash Management Commission:

The Governor’s action  wasn’t required by the decision in McCrory v. Berger.  The court did not find anything unconstitutional in the creation of a Coal Ash Management Commission to oversee decisions on closure of coal ash ponds and coal ash disposal.  The court  only held the method of appointing CAMC members  to be  unconstitutional.  The N.C. Supreme Court has found commission appointments statutes unconstitutional in the past and the solution has been to amend the statute to change the appointment scheme.  In 1982, the N.C. Supreme Court  ruled in Wallace v. Bone  that the General Assembly violated the N.C. Constitution’s separation of powers provisions by designating four seats on the N.C. Environmental Management Commission (EMC) for active members of the legislature.  In response, the General Assembly amended the EMC appointments statute to replace the legislators serving on the commission with citizens appointed by the General Assembly.  Nothing in the court’s decision suggested the EMC must be dissolved and that did not happen; nothing in the decision questioned the validity of past EMC actions.  The decision in McCrory v. Berger likewise  does not hold that actions already taken by the Coal Ash Management Commission — such as hiring staff and entering into contracts  for services —  are void or voidable.

Another separation of powers case still pending in  Wake County Superior Court challenges appointments to the Mining and Energy Commission  (MEC) and specifically asks the court to void the MEC’s past rulemaking actions.   But to date, no  court has ruled that the presence of unconstitutionally appointed members invalidates a commission’s  past acts. The MEC case directly  raises the issue for the first time and could lead to a decision affecting future separation of powers cases. In the meantime, the McCrory administration has chosen to go further than the decision in McCrory v. Berger  requires to  undo the existing organizational, staff and contractual arrangements supporting the Coal Ash Management Commission.  (It isn’t clear whether the McCrory administration’s position on the CAMC  would carry over to support for the plaintiffs seeking to invalidate the Mining and Energy Commission’s past rulemaking actions on similar grounds.)

The General Assembly’s next move may depend on continued legislative interest in providing oversight for DEQ’s coal ash decision making.  In 2014, the General Assembly created the Coal Ash Management Commission to provide independent oversight for DEQ decisions related to coal ash disposal and closure of existing coal ash ponds. At the time, legislators expressed concern about relying entirely on DEQ’s judgment because of controversy surrounding early McCrory administration decisions on coal ash enforcement and a pending federal investigation of relationships between state regulators and Duke Energy. The question is whether those concerns still exist and,  if so,  how the legislature will react to the Governor’s unilateral move to disable the commission. The General Assembly can resolve the separation of powers issue and revive the CAMC by simply changing the CAMC appointment provision to  allow the Governor to make a majority of the appointments.

By forcing the Coal Ash Management Commission to start over, the Governor’s action may make it impossible for the commission to meet its first critical deadline –risk classification of coal ash ponds. The Coal Ash Management Act gave the CAMC final authority to determine the appropriate risk classification of each coal ash pond; the risk classification will determine how quickly the ash pond must be closed and whether the coal ash must be excavated and disposed of in a lined landfill. Only coal ash ponds classified as Low Risk can be closed out by dewatering and capping the ash in place.  Under the law, the CAMC must make a final decision on risk classification of a coal ash pond within 60 days after DEQ sends the commission a proposed risk classification. If the commission does not act within 60 days, DEQ’s proposed risk classification becomes the final classification by default.

Timelines in the law will  require DEQ to submit proposed classifications for all of the coal ash ponds to the  Coal Ash Management Commission by mid-May.  Some proposed classifications may be ready sooner. Even if  new appointments to the CAMC can be made under an amended appointments statute by that time, the Governor’s action means the newly appointed commission will have to reassemble a staff, re-engage consultants and revive basic  operating systems to function.  Unless the General Assembly extends the time for the CAMC to review and act on proposed risk classifications,  the DEQ proposed classifications may become final by default before the commission can act.

After the ash ponds have been classified, the next major set of CAMC decisions under the Coal Ash Management Act  involve approval of final closure plans for each coal ash pond.  The closure plans determine whether coal ash will be excavated and removed from the site or capped in place and  includes approval of technical specifications for final disposal of coal ash. The closure plan may also involve approval of a beneficial reuse project as an alternative to landfill disposal. The law directs the CAMC to make the final decision on  approving a final closure plan based on a recommendation from DEQ.  The law again gives the CAMC a limited time to act on each recommended closure plan; if the commission does not act within the time allowed, DEQ’s recommended closure plan becomes final by default.

If the General Assembly does not intervene to protect the Coal Ash Management Commission’s ability to carry out its responsibilities, the practical result could be a significant change in the way the Coal Ash Management Act works. Delaying the commission’s ability to act in time to affect DEQ’s decisions on closure of coal ash ponds will have the practical effect of ceding all  decision-making back to DEQ.  The original concept of providing  independent oversight of those decisions through the Coal Ash Management Commission will be lost.

To Drink or Not to Drink: A Change in Advice for Well Owners


March 17, 2016. In 2015,  the N.C. Division of Public Health (Department of Health and Human Services) sent letters advising the owners of  369  wells located near coal ash ponds not to drink their well water because of elevated levels of vanadium and chromium-6.  Last week, the Division of Public Health sent letters to those same well owners to withdraw the “do not drink” advisory.  Some questions and answers on the conflicting advice below.

What are vanadium and chromium-6 (Cr-6)? Both elements occur naturally in the environment and can be found in coal ash. Both may  be concentrated in the air or in groundwater as a result of industrial activities.  Inhalation of Cr-6 (or hexavalent chromium) has been associated with increased risk of lung cancer. In 2010,  the U.S. Environmental Protection Agency  began a new health study to determine whether ingestion of  Cr-6  in drinking water increases other types of cancer risk. The Erin Brokovitch story of hexavalent chromium contamination in the town of Hinkley, California raised public awareness of Cr-6 as a public health issue. In Hinkley, Pacific Gas & Electric  had used Cr-6 as an additive in cooling water for a natural gas compression station. The  Cr-6 percolated into groundwater from unlined ponds used to store the cooling water, contaminating the town’s drinking water supply. (Levels of Cr-6 in  Hinkley’s groundwater were exponentially higher than concentrations found  in North Carolina  wells.)

Are there drinking water standards for vanadium and  Cr-6? There is no federal drinking water standard for vanadium.   The U.S. Environmental Protection Agency has adopted a drinking water standard for total chromium of 100 parts per billion (ppb);  the standard covers combined concentrations of chromium-3 (a nutritional element found in plant material) and chromium-6.  Water systems required to meet federal Safe Drinking Water Act standards monitor  total chromium levels, but not necessarily  Cr-6. Nationally, only the State of California  has adopted a specific drinking water standard for Cr-6. In 2014, after  years of  study prompted by the Hinkley contamination,  California adopted a standard of 10 parts per billion for Cr-6 in drinking water — 1/10th the concentration allowed under the federal drinking water standard for total chromium.

How are  N.C. groundwater standards different from  federal drinking water standards?  In part,  the two sets of standards serve different purposes. Drinking water standards adopted by U.S. EPA under the Safe Drinking Water Act only apply to the treated water that public water systems  provide to their customers.  Under the law, “public water system” means any system providing water to 15 or  more connections or to 25 or more people whether the system is  operated by a local government or a for-profit water utility.  Federal drinking water standards do not apply to privately owned water supply wells serving individual homes or businesses.

N.C.’s  groundwater standards are used to identify unsafe levels of groundwater contamination;  set goals for groundwater remediation; and advise well owners on use of water from affected wells.  Most N.C. groundwater standards track the federal drinking water standard for the same contaminant, but in a few cases the state has adopted a more stringent groundwater standard or has adopted a groundwater standard for a contaminant that has no corresponding drinking water standard.  Leading up to the well testing around coal ash ponds, N.C. had no groundwater standard for vanadium and no specific standard for Cr-6. although the state had a groundwater standard of 10 ppb for total chromium (more stringent that the 100 ppb drinking water standard for total chromium.)

How does N.C. set groundwater standards?  The N.C. Environmental Management Commission has adopted state groundwater standards as rules. Since existing groundwater standards may not address every potential contaminant,  the rules also create a process for developing  a temporary  standard  — an Interim Maximum Allowable Concentration or “IMAC” —  to address an unregulated contaminant.  Epidemiologists in the N.C. Division of Public Health generally develop a recommended IMAC based on review of human health effects such as toxicity and increased cancer risk.

Why did the  Division of Public Health send “do not drink” letters in 2015 based on  vanadium and chromium-6?   Since no state groundwater standard or federal drinking water standards existed for vanadium and  Cr-6, DEQ  asked the Division of Public Health to develop interim groundwater standards (the IMACs described above)  to be used in assessing wells around the coal ash ponds. Division of Public Health calculated a standard of 0.07 ppb for Cr-6 and 0.3 ppb for vanadium.  In each case, the deciding factor was the concentration associated with an  incremental increase in cancer risk. The table below shows the IMAC standard compared to the federal Safe Drinking Water Act standard and the N.C. groundwater standard.

Contaminant Fed. Drinking Water Standard N.C. Groundwater Standard IMAC
Vandadium No standard No standard 0.3 ppb
C.hromium-6 None –Total Cr 100 ppb None – Total Cr 10 ppb 0.07 ppb

Why did Division of Public Health withdraw the “do not drink” letters?  None of the  well owners who received “do not drink” letters  based solely on the vanadium and Cr-6 IMAC standards have well water that would violate Safe Drinking Water Act standards for a public water system.  DEQ has reported that 70% of public water systems in the U.S. exceed the IMAC standards set by Division of Public Health, including several large public water systems in North Carolina. (The information, provided in a report to the legislature’s Environmental Review Commission,  did not indicate how many of those systems exceeded the IMAC standard for vanadium versus Cr-6. You can find the entire DEQ presentation to the Commission  here.)

The gap between the IMAC standards and Safe Drinking Water Act standards meant that well  owners were being advised not to drink water that meets current drinking water standards and could lawfully be provided to customers of a  public water system.   As a practical matter, that also  means the well owners may not have access to an alternative water supply of any better quality  since  the nearest public water system also may not meet the IMAC standards.

None of this  means the analysis done by the Division of Public Health in developing the IMACs was wrong. Environmental and public health standards change with additional knowledge; the fact that the U.S. Environmental Protection has undertaken a new health study of Cr-6 in particular suggests some question about the adequacy of the  federal drinking water standard based solely on total chromium.  The standards adopted by EPA and the states also sometimes involve compromise between the most protective health-based standard and the practicalities (and cost) of meeting that standard.

Making Sense of a Coal Ash Penalty

March 8, 2016.   The  civil penalty for  groundwater violations around Duke Energy’s Sutton Plant in New Hanover County has taken several unprecedented  twists and turns.  This post looks at the  $25 million civil penalty for groundwater contamination at the Sutton Plant that became a $7 million civil penalty for groundwater violations at all 14 coal ash sites in the state and then a $7 million civil penalty just for the Sutton violations.

Groundwater Enforcement 101.   The Department of Environmental Quality (DEQ) can order remediation of groundwater contamination and assess civil penalties for violation of the state’s  health-based groundwater standards.  Some contaminants (like arsenic) occur naturally; if natural  “background” levels of the contaminant exceed the state standard, the background level becomes the standard. State rules allow for some exceedence of  groundwater standards within the footprint of a waste disposal facility, but set a “compliance boundary” around the facility where the  standards must be met.  Coal ash ponds permitted before 1983 must meet groundwater standards within 500 feet of the ash pond; those  permitted later have a  250-foot compliance boundary.

To assess a civil penalty for coal ash contamination,  DEQ  must show: 1. Contaminants in the groundwater exceed the state standard (which may require determining background levels if the contaminant occurs naturally); 2. Exceedences occur at or beyond the compliance boundary; and 3. Coal ash  caused or contributed to the contamination. State law caps the maximum penalty for a single groundwater violation  at  $25,000.  In setting the specific penalty amount within the cap, DEQ considers a number of penalty factors including the extent of environmental harm;  whether the violation was intentional; and any compliance costs the violator may have avoided.  Since  DEQ can assess daily penalties for continuing violations, the total civil penalty may exceed $25,000  if a violation continues over a period of time.

Now a Little Coal Ash History. The state originally permitted  coal ash ponds as wastewater treatment systems. The ponds receive, treat and discharge  process wastewater and sometimes stormwater.  A coal ash pond functions like  the  settling basins used  in other wastewater treatment systems; the coal ash settles out of the  wastewater slurry,  reducing pollutants in the top layer of pond water.  The utility then discharges wastewater  from the top of the pond to a river, stream or lake under a  Clean Water Act Permit —  the  National Pollutant Discharge Elimination System (or “NPDES”)  permit.  NPDES permits  protect surface water from pollution; since groundwater was never the focus, the  permits  historically required very limited groundwater monitoring around coal ash ponds.

In response to pressure for national coal ash disposal standards,  companies operating coal-fired power plants began a program of voluntary groundwater monitoring in 2006 and provided results to the state.   (As a voluntary program, the power companies alone decided what contaminants to monitor for and where to put monitoring wells.) By  2009,  state water quality officials had become so concerned about the utilities’ groundwater data  that the Division of Water Quality  (DWQ) moved  to put stronger  groundwater monitoring conditions on NPDES permits for coal ash ponds as the permits came up for renewal.  The new permit conditions made monitoring for specific contaminants mandatory and required  DWQ approval of the monitoring plan so monitoring wells would be appropriately placed to identify violations at the compliance boundary.

As DWQ began adding monitoring conditions to permits,  the senior manager in DWQ’s groundwater protection program issued a  memo  explaining how the program would take enforcement actions based on the new groundwater monitoring data. The memo applied to any facility that had operated for a long period of time before being required to do groundwater monitoring.  It  implicitly recognizes that imposing groundwater monitoring conditions  after many years of facility operation may result in immediate detection of groundwater exceedences — giving the operator little opportunity to prevent  a violation. The memo did not completely foreclose  the possibility of a civil penalty for groundwater violations at these facilities, but indicated that  DWQ  may not issue a Notice of Violation (the first step to a penalty) as long as the operator responded to state requests for assessment and clean up of any contamination.

The Sutton Plant Civil Penalty. The Sutton Plant’s wastewater system, consisting of two coal ash ponds built in 1971 and 1984, has had an NPDES  permit since 1977.    For most  of the system’s history,  the  permit only required monitoring for a  limited number of  groundwater quality parameters —  groundwater level, pH, Arsenic, Iron, Total Dissolved Solids, Chlorides and Selenium.   When DWQ renewed the Sutton Plant’s NPDES permit in 2011,  the new permit required monitoring of  additional contaminants (including boron, thallium, and manganese) under a state-approved monitoring plan designed to detect exceedences at the compliance boundary.  In March 2015,  DEQ assessed a record $25 million civil penalty for groundwater violations around the Sutton Plant. The civil penalty  covered a number of different groundwater standard violations over varying periods of time. The earliest violations identified in the assessment  document  dated back to 2009 (for boron) and 2010 (for thallium).    Most of the violations  (for iron, arsenic, selenium, manganese and total dissolved solids)  dated from 2012 or 2013. To reach the  $25 million assessment, DEQ  assessed either $1,000 or $5,000  per day (from initial detection to the assessment date) for each contaminant that exceeded state groundwater standards.

A Big — and Short-Lived — Settlement. Duke Energy  appealed the penalty and several months later  DEQ agreed to a settlement reducing the civil penalty to $7 million.  The most notable thing about the September 2015 settlement agreement was not the penalty reduction, but the fact that the settlement would have resolved all groundwater violations (known or discovered in the future) around all 14 Duke Energy coal ash impoundment sites in the state.  Southern Environmental Law Center (SELC),  on behalf of several environmental organizations, challenged the settlement agreement in court. SELC’s appeal did not contest  the penalty reduction for the Sutton violations, but argued  Administrative Law Judge Phil Berger, Jr. had no authority to approve a settlement agreement affecting issues beyond the Sutton civil penalty.  SELC particularly complained that the settlement agreement affected other coal ash enforcement cases without notice to the parties in those cases — including organizations represented by SELC.  Those enforcement cases dealt with specific actions required of Duke Energy to  address groundwater contamination around coal ash ponds at multiple sites.

Key provisions in the September 2015  DEQ-Duke Energy   settlement agreement

♦ Duke Energy agreed to pay a civil penalty  of $7 million and accelerate groundwater remediation at the Sutton, Asheville, Belews Creek and H.F. Lee plants. The settlement agreement did not set a timeline for the accelerated remediation.

♦ DEQ agreed to dismiss groundwater enforcement cases already pending in superior court related to the Sutton Plant and the Asheville Steam Station. See the SELC appeal of the settlement agreement for more on the relationship between the settlement agreement and pending enforcement cases.

♦ DEQ agreed not to issue Notices of Violation,  notices requiring assessment or remediation, civil penalty assessments or to  take any other enforcement actions against Duke Energy based on groundwater conditions “at any of the Duke Energy Sites” as long as Duke Energy complied  with requirements of the Coal Ash Management Act related to groundwater assessment, remediation and closure of the coal ash basins. Under the agreement, the “Duke Energy Sites” included all 14 coal ash sites across the state.

♦ DEQ agreed not to change groundwater monitoring conditions in existing or future NPDES permits for the coal ash ponds unless required by  court order;  a federal or state law; a rule; or in response to an immediate threat to public health.  Under the agreement, an “immediate threat to public health” had to involve something more than violation of a  health-based groundwater standard.  In effect, the settlement prevented DEQ from using its permitting authority to requiring monitoring for additional contaminants.

♦ DEQ agreed not to use groundwater monitoring data collected under either the NPDES permit conditions or under provisions in the Coal Ash Management Act for any purpose other than classification and closure of the coal ash ponds. In other words, DEQ agreed not to use groundwater monitoring data for enforcement purposes.

Reversing Direction.  In February, Superior Court Judge Paul Ridgeway held a hearing  on SELC’s objections to the Sutton settlement agreement.  Persuaded that the settlement agreement  affected the other enforcement  cases already before him,  Judge Ridgeway indicated an intent to take jurisdiction over the settlement agreement unless Judge Berger  narrowed the scope of his order in the Sutton civil penalty case.   Charlotte Business Journal has  reported  that Judge Berger later issued a revised order at the request of DEQ and Duke Energy.   According to the article, the settlement agreement between Duke Energy and DEQ did not change, but the  order  approving the settlement has been expressly limited to the Sutton civil penalty case.  (I have not been able to find the  revised order  on either the Office of Administrative Hearings  or DEQ website.)  As a result, the $7 million civil penalty now covers only  groundwater violations at the Sutton Plant.

Signs and Portents? DEQ made several unusual decisions in assessing and then settling the Sutton civil penalty case:

The  original $25 million civil penalty for the Sutton groundwater violations broke from past enforcement practices.  State programs  rarely impose daily penalties for newly discovered groundwater violations. Daily penalties are usually reserved for willful, intentional violations and for violators who  fail to quickly address contamination once it has been detected.  DEQ didn’t cite either of those aggravating factors in assessing the original $25 million Sutton penalty.  To reach the $25 million total, DEQ assessed a penalty of either $1,000 or $5,000 a day (depending on the contaminant) from the date of detection to the date of assessment.  (The contamination persists today and will until coal ash on the site has been removed, which everyone understands will require more time.)  The question is whether DEQ’s very aggressive penalty for the Sutton violations indicates a change in enforcement policy that may affect  other groundwater cases.

There doesn’t seem to be any precedent for DEQ agreeing –as it did in the original Sutton settlement — to limit its own permitting and enforcement authority to settle a civil penalty case.  State agencies often settle  civil penalty cases for a lower penalty amount. In the Sutton settlement, DEQ  also agreed not to change groundwater monitoring conditions on Duke Energy’s NPDES permits except in very narrow circumstances. Most of those circumstances required  some outside force  — federal law, a court order — to compel the change. In effect, DEQ  gave up the ability to use its permitting authority to  require monitoring for additional contaminants. The department also agreed not to issue Notices of Regulatory Requirements (orders for assessment and remediation of contamination)  or take  new enforcement actions against Duke Energy based on coal ash contamination at the 14 sites in N.C. The settlement agreement was conditioned on Duke Energy complying with provisions in the Coal Ash Management Act on  groundwater assessment and corrective action, but those requirements assume application of state groundwater regulations. It isn’t clear why DEQ would agree to give up use of normal groundwater enforcement tools like the Notice of Regulatory Requirements. Limits on DEQ use of groundwater data for enforcement purposes could have affected the state’s ability to address  groundwater problems discovered later.

What Does it Mean?  Assuming Judge Berger’s revised order has set much of the Sutton settlement agreement aside, the Sutton case is mostly  interesting as an insight into DEQ’s enforcement decision-making. It is hard to identify a consistent principle that would explain both  DEQ’s very aggressive use of civil penalty power in the first instance and DEQ’s willingness to  give up significant permitting and enforcement authority  to settle the  case. The question is whether the Sutton decisions  were peculiar to it or have broader implications.
