The US Environmental Protection Agency (EPA) has published a change to the Resource Conservation and Recovery Act (RCRA) regulations in connection with the definition of solid waste. The final rule revises the definition of solid waste to exclude certain hazardous secondary materials from regulation under Subtitle C of RCRA. The revised definition of solid waste codifies the factors to be used in determining whether recycling is legitimate. EPA proposed 2010 rule changes offer two approaches for addressing risks of coal ash management under RCRA, one under Subtitle C and the other under Subtitle D. EPA has primary responsibility for the permitting of hazardous waste treatment, storage, and disposal facilities until it authorizes a state to operate portions or all of the hazardous waste program under Subtitle C. Subtitle D provides for the permitting and monitoring of municipal and nonhazardous solid waste. RCRA does not authorize EPA to issue federal permits for disposal of Subtitle D wastes.

Between 1994 and 2008 Texas' environmental agency, the Texas Commission on Environmental Quality, submitted more than 25 New Source Review program changes to EPA Region 6 for approval into the Texas SIP but did not receive timely approval. This failure by the EPA to take action to approve or disapprove created a "SIP gap". An industry group in Texas challenged this "SIP gap" in court and the results of this challenge have been escalated to "political" levels. The DC Circuit has set the briefing schedules for the four lawsuits opposing EPA's greenhouse gas (GHG) regulations, i.e., Petitioners brief due arguing that NSR should not apply to GHG's; Petitioners brief due challenging the endangerment finding; Petitioners brief due challenging the vehicle emissions rule; and Petitioners brief due for tailoring rule and the Johnson memo. The issues that Texas and the EPA are currently in disagreement over and attempt to explain each side's position rationale are discussed. This is an abstract of a paper presented at the 104th AWMA Annual Conference and Exhibition 2011 (Orlando, FL 6/21-24/2011).

The acronyms MSS and SSM are used frequently and often interchangeably nowadays. SSM is commonly found in many state environmental regulations as startup, shutdown, and malfunction, and EPA has referred to it as startup, shutdown, maintenance, and malfunctions. MSS, as used in Texas, refers to emissions resulting from maintenance, startups, and shutdowns. Texas has taken an aggressive approach to permitting MSS emissions. They thus amended their General Rules (30 Texas Administrative Code Chapter 101(30 TAC 101) by adding a schedule whereby industries in certain Standard Industrial Classification (SIC) codes have to submit MSS applications to obtain an affirmative defense for planned MSS activities, e.g., Standard Industrial Classification (SIC) code 2911 (Petroleum Refining) by 1-5-2007; and SIC codes 1311 (Crude Petroleum and Natural Gas), 1321 (Natural Gas Liquids), 4612 (Crude Petroleum Pipelines), 4613 (Refined Petroleum Pipelines, 4922 (Natural Gas Transmission), 4923 (Natural Gas Transmission and Distribution by 1-5-20 12. A discussion covers the origins of the regulatory determination of whether such emissions are authorized or not; state programs, showing the many different ways the issue is approached from the standpoint of routine excess emissions or emissions due to upsets.

The history of in-stack particulate matter (PM) measurement methods began in 1971 with promulgation of the US EPA Reference Method 5, following on the heels of promulgation of the NAAQS for total suspended PM earlier that same year. In April 1990, the EPA promulgated Reference Method 201/201A as the stack test method for filterable PM10. Then in December 1991, EPA promulgated Reference Method 202, which is typically used in conjunction with Method 5 or Method 201A to measure filterable plus condensable PM. The revised version of Method 202 ensures consistency of method application and is intended to improve measurement precision by reducing sulfate artifact formation. On 4/8/2014, the EPA issued interim guidance addressing the processing of Method 202 results for regulatory permitting and compliance purposes. The interim guidance essentially allows for a higher maximum correction level, if dictated by the appropriate blank value, with the intent of reducing overestimation of condensable PM emissions.

Hydraulic fracturing is a process that has opened access to numerous oil and gas reserves that in the past would not have been economically feasible to develop. With growing energy demand worldwide,the economic driver to continue to identify and develop oil and gas reserves will not diminish. In the United States, a regulatory framework is in place for either federal or state level regulatory oversight of the hydraulic fracturing process; however, the issue is how much regulatory oversight is warranted. © 2011 Air & Waste Management Association.

Several specific environmental issues involved in the use of coastal and marine spatial planning in certain applications are discussed. Coastal and marine spatial planning is a process of analyzing and allocating the spatial and temporal distribution of human activities in marine areas to achieve economic and social objectives that have been specified through a political process. A Marine Spatial Planning Stakeholder Analysis has been conducted for the US National Oceanic and Atmospheric Administration's (NOAA) Coastal Services Center with a report issued in January 2010 to address various environmental issues. This evaluation has identified a number of issues involving marine spatial planning, including a significant foundation for regional marine spatial planning being laid and the conservation of ecosystems being a driver for is a common marine spatial planning.

The recent NAAQS proposal for O3 focuses on inconsistent and infrequent physiological changes observed in controlled human exposure studies that are often too mild to be considered clinically relevant to justify lowering the 8-hr primary O3 NAAQS. To evaluate EPA's proposal to reduce O3 NAAQS, key studies cited by EPA in the Policy Assessment for the Review of the Ozone National Ambient Air Quality Standards were reviewed for evidence that O3-attributable health effects occur at concentrations below the current O3 NAAQS of 75 ppb. This is an abstract of a paper presented at the AWMA's 107th Annual Conference & Exhibition (Long Beach, CA 6/24-27/2014).

An important aspect of the hydraulic fracturing process is identifying and securing sufficient water resources. With the ever increasing demands for higher quality water resources for domestic and agricultural needs, alternative water sources including brackish groundwater and water reuse options are being evaluated and used for hydraulic fracturing operations. To access alternate water sources both the availability and suitability of the water resource must be addressed. Available alternate water sources are first identified within a reasonable distance to the wells that will be hydraulically fractured. Once identified, the alternate water source must be evaluated to determine if it is suitable (in terms of both quality and quantity) to meet the hydraulic fracturing requirements. If all conditions are met, the alternate water resource will provide a viable solution to meet the water needs of the hydraulic fracturing operation and at the same time minimize impacts to more sought-after water resources. Examples of utilizing available groundwater information from public domain sources to identify brackish groundwater resources and to map the horizontal and vertical extent of these resources are presented. The classification of brackish groundwater includes a wide range of water quality parameters and only some of the brackish groundwater falls within the technical specifications needed the hydraulic fracturing operation. Water reuse in the form of treated wastewater effluent can provide a suitable water resource for the hydraulic fracturing process. Examples of the identification and evaluation of wastewater effluent sources are presented. From initial identification of potential wastewater effluent resources through the evaluation of these identified resources to determine the viability to use these resources for the hydraulic fracturing process is presented. Sustainable use of water resources is important under all circumstances with heightened concern when drinking water and irrigation quality water is limited from higher demand and/or draught conditions. The effective and appropriate identification and evaluation of alternate water sources is critical to the successful hydraulic fracturing process. This paper presents field implemented processes and procedures used to identify and evaluate brackish groundwater and treated wastewater effluent to meet hydraulic fracturing water needs.
