Background of Open Burning and Open Detonation (OB/OD) under RCRA
1978 EPA proposed to ban all open burning of hazardous wastePublic comments (including DOD and private sector): Need to allow OB/OD of energetic wastes in cases where there are no safe alternatives1980 Final Rule: OB/OD of all hazardous waste is prohibited, except for explosives/propellants when there are no safe alternatives or it is an emergencyThis OB/OD exemption for energetics was considered temporary pending development of alternative technologies (preamble to final rule)

What is a Resource Conservation and Recovery Act (RCRA) Permit?
RCRA Permits are built from a standard foundation of RCRA regulatory requirements, then customized per facility.The foundation requirements are 40 CFR Parts 260 to 270.Authorizing/empowering the state equivalent requirements, 40 CFR Part 271.States can become authorized to implement the RCRA program and thus states typically issue RCRA permits.The Permit Writer must ensure that:A permit is consistent with the regulatory requirements.A permit identifies what is regulated, approves the facilities’ chosen or modified regulatory controls (e.g., design, monitoring), and speaks to how regulatory compliance will be measured.A permit is not issued if the application or results of inspection demonstrate noncompliance or has conflicting information.
What is a RCRA Permit?
The Permit establishes a detailed specification of parameters established to measure compliance (e.g., the remedy to be constructed, groundwater cleanup standard to be met).The Permit includes Schedules of Compliance to complete specified documentation to be submitted, construction, investigations, and other remedy decisions or work.The Permit may also impose unique “Omnibus Authority” conditions.Section 3005(c)(3) of RCRA, referred to as the “Omnibus Authority,” requires that each RCRA permit contain terms and conditions as the Administrator or State Director determines necessary to protect human health and the environment. This provision, codified at 40 CFR 270.32(b)(2), and its associated information requirement at 40 CFR 270.10(k), gives permit writers the authority to impose permit conditions in addition to applicable permit standards found in 40 CFR 264, if needed for the permit to be protective.
Who Needs a RCRA Permit?
RCRA requires a permit for the treatment, storage, and disposal of any hazardous waste identified or listed in 40 CFR Part 261.Owners or operators of facilities that treat, store, or dispose of hazardous waste must obtain an operating permit under Subtitle C of RCRA.Treatment, storage, or disposal facilities (TSDFs) in existence on or beforeNovember 19, 1980,operate under interim statusuntil a final permit decision is made.New TSDFs (i.e., those that were not in operation on or before November 19, 1980) are ineligible for interim status and must receive a RCRA permit before construction can commence.

RCRA Permit Conditions
All RCRA permits generally have conditions that address the following:General facility standards (e.g., waste analysis, security, inspections, training, requirements for ignitable-reactive-incompatible wastes, location standards)Preparedness/preventionContingency plan and emergency proceduresRecordkeeping/reportingCorrective action/site remediation of contaminated media
RCRA Permit Conditions
General permit conditions applicable to all permits (continued)Closure/post closureFinancial assuranceUse and management of tanks/containersMany other requirements based on the specific operations and design of the facility
Types of OB/OD RCRA Permit Conditions
Treatment operations such as OB/OD thatdo nothavespecificregulatory design/operation requirements must be permitted pursuant to 40 CFR 264, Subpart X requirements.Subpart X stipulates that permits for these “miscellaneous units” must contain terms and provisions as necessary to protect human health and the environment.
Types of OB/OD RCRA Permit Conditions
This includes permit conditions that generally cover requirements applicable to:Treatment unit design, operation, and monitoringPrevention of releases to ground, surface water and air that pose unacceptable riskResponses to releases of hazardous waste or hazardous constituentsOB/OD permit limits differ and are site-specificHowever, all permits must ensure protection of human health and the environment
Types of OB/OD RCRA Permit Conditions
Example OB/OD operating conditions from permits – each permit will not necessarily include all these requirementsWaste restrictions (e.g. energetic/reactive waste only, on-site generated waste only)Daily/annual/event limits on amount OB/OD’dSome have waste concentration limitsDays/hours of operation restrictions# of days per week, during daylight hours onlyWeather condition restrictionsWind speed, rain forecast, lightening, etc.Some prohibit operations on O3action days
Types of OB/OD RCRA Permit Conditions
Example OB/OD operating conditions from permits – each permit will not necessarily include all these requirementsFire hazard managers required on scenePeriodic soil, groundwater monitoringRequirements specific to risk thresholdsOperations shall not cause carcinogenic risk of 1X10-6to be exceeded offsiteOperations shall not cause non-carcinogenic chronic hazard index of 1.0 to beexceeded offsiteSome permits require periodic assessments of the info used to model pollutant transport and risk, including emission factors and appropriateness of risk determination assumptions
Types of OB/OD RCRA Permit Conditions
Example OB/OD operating conditions from permits – each permit will not necessarily include all these requirementsNotification requirements, access restrictionsSiren, clearing nearby river of boaters, etc.Signs, gates, surveillance teamsPublic complaint proceduresClearing dry grass, leaves, and other combustiblesWater run on/off controls (stormwater control)Pre and post burn/detonation inspectionsSpilled waste management requirements

Types of OB/OD RCRA Permit Conditions
Example operating conditions specific to OBBurn pad design (height, refractory design, precipitation covers, waste kept below critical height to prevent detonation)Hazardous waste shall not be used as burn pan accelerantsBurn box shall remain closed when waste is not being burned/treatedSome permits require periodic assessments of theavailability of alternatives to OB/OD

Alternative Technologies Project
Assessing alternative technologies that may be used in place of OB/ODParameters of assessment include:Technology type with applicable subcategorizations ;Type of waste and constituents the technology is designed for (e.g., bulk energetics including:tetrytol, M28 propellant, M8 propellant, or fireworks, flares, etc.);The scale with which the technology has been used(e.g., bench, pilot, full-scale use);Throughput capability (e.g., pounds per hour);Whether the technology requires pre-treatment and/or post-treatment technologies;Output associated with technology (e.g., air emissions, hazardous or solid waste, wastewater);
Parameters (continued)Whether or not approved for use by the Department of Defense Explosives Safety Board (DDESB);The manufacturer of the technology including contact information;Cost to purchase, install, and operate the treatment unit;Where the technology is or has been used and the type of waste treated;Ability to treat: thin-walled; thick-walled; bulk itemsAbility to treat unarmed v. armed munitionsMost importantly, the focus is the waste stream to be treated so that we can determine which technology type(s) are suitable.
