4 Existing Federal and State Regulations Governing Petcoke Operations Petcoke operations are regulated by a multitude of existing Federal and state programs as listed below. — Clean Air Act (broadly prohibiting air pollution). — Fugitive dust/fugitive emissions (Fugitive Dust Control Plans). — Limits on duration or opacity of “visible emissions.” — Title V air operating permits. — Clean Water Act—National Pollution Discharge Elimination System (NPDES) including storm water runoff. — Fire prevention codes (typically are based on either the International Fire Code (IFC) or National Fire Prevention Association (NFPA) standards). With respect to the particular circumstances of a site storing and/or handling petcoke, local, state, and federal laws should be reviewed. 5 Fugitive Dust Management Plan Sites that store and/or handle petcoke should consider developing a fugitive dust management plan. The management plan should consider including: — a map showing the location of the facility, location of storage areas, normal traffic patterns to access storage locations, and location of loading/unloading and transfer points; — a description of the dust suppression system(s) (i.e. control measures, devices, and technologies) the site uses to minimize/control fugitive dust; — storage, handling, and transportation operations; — the maintenance and reliability programs for the petcoke handling equipment; — the maintenance and reliability programs for the emissions control measures/equipment; — the housekeeping measures employed to prevent fugitive dust; — water runoff management options.1 Scope The purpose of this document is to provide guidance on operating and maintenance practices for the storage and handling of petroleum coke (petcoke). In particular, guidance is provided on the management of airborne particulate matter emissions and water runoff from petcoke storage facilities. A variety of techniques is presented and should be applied based on knowledge of specific facility and product conditions. These techniques are known to be effective depending on specific conditions at the site include average wind speeds and climate, moisture content of the material, etc. 2 References The following referenced documents are indispensable for the application of this document.

This coke is also termed “green” coke or “fuel grade” coke. 3.3 roadway Any road used for repeated travel by car, truck, or off-road mobile heavy equipment but does not mean any part of a pad on which petcoke is staged or stored.
6 Primary Practices to Control Petcoke Emissions—Storage 6.1 General Petcoke storage may occur at a variety of locations including the point of production, an intermediate logistics terminal, and the end user facility. At each of these locations, maintaining the optimum moisture content of petcoke is a key practice required to control petcoke fugitive emissions. There are three primary techniques that should be considered to maintain optimal moisture content and control potential petcoke emissions (i.e. fugitive dust) during storage: 1) pile maintenance, 2) wetting with water, and 3) treating with an anti-dust chemical agent. 6.2 Pile Maintenance Pile maintenance is important as a method to control potential fugitive dust. Proper maintenance of petcoke piles will help reduce the potential for fugitive dust emissions, particularly when combined with wetting or anti-dust chemical agent practices, as discussed in 6.3 and 6.4. More specifically, the following should be considered with regard to properly maintaining a petcoke pile: — pile height consistent with facility’s water application capabilities, — shaping of the piles to remove peaks and sharp edges, — pile compaction, — reclaiming practices designed to reduce potential dust emissions, — pile stacking practices designed to reduce potential dust emissions (e.g. minimizing drop height from stacking conveyors).
