Here is how we can help: More specifically, this guidance document conveys how EPA generally intends to exercise its discretion in implementing RCRA statutory and regulatory provisions concerning combustion facilities subject to RCRA. EPA designed this guidance to explain and clarify national policy on issues related to EPA's obligation to ensure that operating permits granted to combustion facilities contain conditions necessary to protect human health and the environment.

To obtain a permit, as a first step the facility must submit a detailed, multi-volume permit application, providing detailed engineering and other data which specify how the incinerator is designed and how it will operate.

The application must include a trial burn plan to evaluate the emissions from Mact ppt process, and to demonstrate that the incinerator meets DRE.

Public hearings must be held at the time of submission of the application to get the views of those near the site. The emission results from the trial burn are then evaluated in a comprehensive risk assessment study that considers both direct and indirect risks to the public.

Finally, after all regulatory requirements have been met to assure protection of public health and the environment, a final operating permit is issued. The incinerator must operate at all times in accordance with its permit.

This assured, in part, by extensive and sophisticated control equipment, continuously recorded monitoring and automatic waste-feed cutoffs discussed below. Further assurance is provided by frequent inspections by the regulatory agencies. In addition, most commercial incineration facilities maintain an open door policy that provides public access to the facility on virtually a daily basis.

Community involvement and outreach is an integral part of facility operations, with many facilities conducting household hazardous waste collection days and technical seminars for their local communities. The parameters demonstrated in the trial burn then become the parameters specified in the permit, which govern subsequent operations.

During a trial burn, which is conducted under direct, on-site regulatory agency supervision, measurements are taken of the waste feed characteristics and volumes; combustion temperatures; combustion gas velocity which is a key element in determining combustion efficiency ; levels of carbon monoxide COhydrogen chloride HClheavy metals and particulates in the stack emissions; and other important parameters, particularly the emissions of principal organic constituents POHCs.

POHCs are difficult-to-burn compounds that are easily detected.

They are selected by the regulatory agency for each waste feed tested. Successful combustion of those POHCs assures that the incinerator, in its daily operations, will properly destroy the hazardous constituents in the waste feed those POHCs represent. Several means are used to project a worst-case performance test during the trial burn.

First, POHCs are selected from constituents judged to be the most difficult to burn. Secondly, waste feeds are selected to contain maximum expected levels of ash and chlorine. These two characteristics directly relate to the capability of the APCS to achieve the particulate and hydrogen chloride HCl emission limits.

Thirdly, the incinerator is operated during the trial burn at the projected worst case limit of the expected range for each critical operating parameter. As a result of these stringent test burn requirements, there is assurance that the permit will specify operating conditions that both 1 protect health and the environment and 2 were demonstrated during the trial burn, under worst-case circumstances.

In fact, most incinerators demonstrate a DRE of A DRE of In fact, EPA reports that "destruction and removal efficiencies reported for incinerators are almost entirely the result destruction [in the incinerator] rather than removal" into the ash or other residues. EPA sets a maximum acceptable risk level that is 10 times more protective than what is allowed for other types of environmental permits or approvals.

The risk assessment must address both direct inhalation exposure of the general public, as well as indirect pathways.

Indirect pathways are based on deposition of pollutants to local farmlands and waterways, and uptake of these pollutants in the food chain cattle, fish, vegetables.

Conservative assumptions are built into the risk assessment to ensure that the conclusions are protective of public health. The emissions modeled in the risk assessment must include metals, dioxin, and the other products of incomplete combustion PICs.

PICs are organic compounds that are formed at trace levels in the combustion process that are not totally destroyed. They are present at extremely low levels parts per billion or less and modeling in the risk assessment ensures that they are not present at levels that are harmful to the environment.

In addition to these required operating parameters, others are typically included in incinerator permits as well. These include, as a minimum, carbon monoxide in the stack, combustion temperature and normally excess oxygen, combustion gas velocity, critical APCS control parameters, and others determined by the permitting agency to be necessary to ensure that the required performance standards are met.

Almost invariably, the permit will include other emission limits, such as for carbon monoxide and various metals, and may specify other, more stringent limits. A risk analysis is conducted, based on the projected emissions of metals, HCl, etc.Summary of RICE NESHAP Rule.
