|December, 2010, Vol 13, No 4|
The Air Quality Advisory Council meeting was held October 27 at the DEQ headquarters in Oklahoma City, Oklahoma. Several rule proposals were presented by the AQD Rules and Planning staff, including both emergency and permanent changes. Many of the proposals were held over to the January 19, 2011 Council meeting, as further review is needed.
Fees for Toxics
The Department also proposed to add a new section to Subchapter 7 to clarify that GHG is excluded from the minor facility permitting program. It is not excluded if it is necessary to set enforceable limits to keep GHG emission levels at a facility below the applicability threshold levels for the PSD construction permit program or the Part 70 operating permit program. At this time, EPA does not have a GHG permitting program for minor facilities.
The Department proposed to add a definition for "greenhouse gas" or "GHG" to Subchapter 1. These rule proposals for Subchapters 1, 7, and 8 were recommended as emergency rules by the Council to be forwarded to the Environmental Quality Board (EQB) for its consideration at the November 16, 2010 meeting. The staff felt emergency rulemaking was necessary due to requirements of the State's rulemaking process, which would require the permanent rules to take effect in July 2011, which is after the January 2, 2011 federal implementation date. Therefore, owners or operators of a large number of smaller sources of GHG that would be exempt by the GHG tailoring rule, could possibly interpret the Department's current rules to require them to obtain permits for new or modified sources of GHG from January 2, 2011 until the proposed modification becomes effective as a permanent rule change. The State's permitting programs could be perceived to be more stringent than the federal programs during this period.
The emergency rules were adopted by the EQB at its November 16 meeting. The hearings on the permanent modifications of Subchapters 7 and 8 for the GHG proposal were held over until the January 2011 Council meeting.
Incorporation by Reference
Trevor Hammons, DEQ Environmental Attorney, gave an overview of upcoming proposed changes to the Lead-Based Paint rules in Chapter 110 of the Oklahoma Administrative Code. The new federal regulations add Renovation, Repair and Painting (RRP) Requirements in the Code of Federal Regulations. The state rulemaking would ensure that the rule is no more stringent than the federal rule and would incorporate changes to be consistent with the Department’s current rules.
The next Council meeting and public hearing will be held on Wednesday, January 19, 2011, at DEQ headquarters in Oklahoma City.
DEQ will host its annual emission inventory workshop on Thursday, January 20, 2011, at the Metrotech Springlake Campus in Oklahoma City and again on Thursday, February 3, 2011, at the OSU-Tulsa campus. In a change from last year, the main workshop, held from 9 am to noon, will precede an optional Redbud session for new users between 1 pm and 4 pm on each day.
The morning session will cover training on how to identify emission units using a permit, ways to gather pertinent information and ways to use the information to build an emissions inventory, emission inventory policy updates, terms and concepts and improvements in Redbud. The afternoon session will offer a Redbud overview for new users and hands-on assistance to participants who need help with inventories. Afternoon attendees are encouraged to bring their laptops and Redbud passwords to follow the data entry and submittal process. Wi-Fi internet access will be available. Both sessions will conclude with a question-and-answer period.
Redbud is Oklahoma’s web-based electronic emissions reporting system. More details on the workshop are available at http://www.deq.state.ok.us/AQDnew/emissions/2011Workshop.html. To register, please email Michelle Horn or call (405) 702-4176 or email Carrie Schroeder or call (405) 702-4178.

Changes Coming January 2011
New Annual Compliance Certification and Semi-Annual Monitoring & Deviation Report Forms
Major, or Title V sources of pollutants are required to submit Annual Compliance Certifications and Semi-Annual Monitoring & Deviation Reports. Please be aware that beginning January 2011 new Title V reporting forms will be available on the DEQ website: http://www.deq.state.ok.us/AQDnew/whatsnew/index.htm. The new Annual Compliance Certification form will replace current DEQ Forms #100-902 through #100-919. The Semi-Annual Monitoring & Deviation Report form will be a revised version of the current form. More information will be available soon.
Oklahoma remains in attainment for ozone standards under the National Ambient Air Quality Standard (NAAQS). The NAAQS is set at 0.075 parts per million (ppm) of ozone allowed to be compliant and in attainment status. To determine the NAAQS, the Department of Environmental Quality takes the averages for concentrations of ozone measured in an eight hour period and then averages the fourth highest readings across a three year period. If the average of the concentrations is higher than 0.075, the area is considered nonattainment. The chart below shows the highest four daily eight hour average concentrations at each of the DEQ ozone monitoring sites in 2010. It also shows the fourth highest concentrations for the years 2007 through 2009. The columns marked 07-09 Avg. 4th Highs and 08-10 Avg. 4th Highs are all in attainment with the NAAQS because their value is less than .076 ppm. The column marked 2010 critical value shows the number a reading would have to reach that when averaged with the other columns, would add up to more than 0.075 ppm, making the site non-attainment. The three year averages of the 4th high concentrations for 2008-2010 show that no sites are over the .075 ppm eight hour average standard.
Ozone concentrations are influenced by the weather. Stagnation and the transport of pollutants from other areas both play major roles in causing ozone levels to rise. Oklahoma’s ozone season of 2010 contained little stagnation and transport as the upper winds were unusually consistent and strong from the west.
The 2010 ozone season began in May with two days showing concentrations of ozone above 0.075 ppm eight hour average. June had no days over .075 ppm eight hour average. One day in July and two days in August ozone levels rose above the .075 ppm eight hour average.
Oklahoma’s designation as attainment with the ozone NAAQS may be short lived. EPA has announced that it is reconsidering and will tighten the ozone standard before the 2011 season.
The EPA’s new Renovation, Repair and Painting (RRP) rule regulates activities that might disturb lead-based paint in pre-1978 housing, schools and certain other child-occupied facilities. These activities can include sanding, painting, remodeling and window replacement. Prior to 1978, lead was commonly used in paint as well as other common materials such as gasoline. Lead is a toxic metal that has been proven to cause a range of health effects, from behavioral problems and learning disabilities, to seizures and death. Lead poisoning can affect anyone, but pregnant women and children six years old and under are most at risk. No safe level of lead has been established.
Before the promulgation of the RRP rule, there was no mechanism to protect housing occupants and renovation workers from the accidental exposure to lead-based paint dust. The RRP rule establishes safe work practices and training requirements for renovation workers, requires certification of renovation firms, and requires notification of housing occupants when lead-based paint may be present.
Since 1996, the DEQ has regulated all lead-based paint removal and abatement activities in Oklahoma through the Air Quality Division’s Lead-Based Paint unit. This unit will use their expertise in the current program to insure that the new RRP rule is smoothly implemented and provides protection from lead-based paint to housing occupants while providing a one-stop shop for firms and workers in the renovation industry. Questions about the scope of the rule, training and certification requirements or other lead-based paint information can be obtained by calling the Lead-Based Paint Program at 405-702-4100.
