[64 FR 31898, June 14, 1999]

40 CFR 63.1341 Definitions. All terms used in this subpart that ar e not defined in this section have the meaning given to them in the CAA and in subpart A of this part. Alkali bypass means a duct between the feed end of the kiln and the preheater tower through which a portion of the k iln exit gas stream is withdrawn and quickly cooled by air or water to avoi d excessive buildup of alkali, chloride and/or sulfur on the raw feed. This may al so be referred to as the "kiln exhaust gas bypass". Bagging system means the equipment which fills bags with portland cement. Clinker cooler means equipment into wh ich clinker product l eaving the kiln is placed to be cooled by air supplied by a forced draft or natural draft supply system. Continuous monitor means a device which continuously samples the regulated parameter specified in §63.1350 of this subpart w ithout interruption, evaluates the detector response at least once every 15 seconds, and computes and records the average va lue at least every 60 seconds, except during allowable periods of calibration and except as defined otherwise by the continuous emission monitoring system performance specifications in appendix B to part 60 of this chapter. Conveying system means a device for tr ansporting materials from one piece of equipment or location to another location within a facility. Conveying systems include but are not limited to th e following: feeders, belt conveyors, bucket elevators and pneumatic systems.MDAQMD Federal Operating Permit RIVERSIDE CEMENT COMP ANY – Oro Grande Plant Permit Number: 1200003

III-260 Conveying system transfer point means a point where any material including but not limited to feed material, fuel, cli nker or product, is transferred to or from a conveying system, or between separate parts of a conveying system. Dioxins and furans (D/F) means tetra- , penta-, hexa-, hepta-, and octachlorinated dibenzo dioxins and furans. Facility means all contiguous or ad joining property that is under common ownership or control, including propertie s that are separated only by a road or other public right-of-way. Feed means the prepared and mixed materials, which include but are not limited to materials such as limestone, clay, shale, sand, iron ore, mill scale, cement kiln dust and flyash, that are fed to the kiln. Feed do es not include the fuels used in the kiln to produce heat to form the clinker product. Finish mill means a roll crusher, ball and tube mill or other size reduction equipment used to grind clinker to a fi ne powder. Gypsum and other materials may be added to and blended with clinke r in a finish mill. The finish mill also includes the air separator associated with the finish mill. Greenfield kiln, in-line kiln/raw mill, or raw material dryer means a kiln, in-line kiln/raw mill, or raw material dryer for which construction is commenced at a plant site (where no kilns and no in-line kiln/raw mills were in operation at any time prior to March 24, 1998) after March 24, 1998. Hazardous waste is defined in §261.3 of this chapter. In-line kiln/raw mill means a system in a portland cement production process where a dry kiln system is integrated with the raw mill so that all or a portion of the kiln exhaust gases are used to perform the drying operation of the raw mill, with no auxiliary heat source used. In this system the kiln is capable of operating without the raw mill operating, but the raw mill cannot operate without the kiln gases, and consequently, the raw mill does not generate a separate exhaust gas stream. Kiln means a device, including any a ssociated preheater or precalciner devices, that produces clinker by heati ng limestone and other materials for subsequent production of portland cement. Kiln exhaust gas bypass means alkali bypass. Monovent means an exhaust configurati on of a building or emission control device (e. g. positive pressure fabric fi lter) that extends the length of the structure and has a width very small in re lation to its length (i . e., length to width ratio is typically greater than 5:1). The exhaust may be an open vent with or without a roof, louvered vents, or a combination of such features.New brownfield kiln, in-line kiln raw mill, or raw material dryer means a kiln, inline kiln/raw mill or raw material dryer for which construction is commenced at a plant site (where kilns and/or in-line kiln/raw mills were in operation prior toMDAQMD Federal Operating Permit RIVERSIDE CEMENT COMP ANY – Oro Grande Plant Permit Number: 1200003

III-261 March 24, 1998) after March 24, 1998. One-minute average means the average of thermocouple or other sensor responses calculated at least every 60 seconds from responses obtained at least once during each c onsecutive 15 second period. Portland cement plant means any facility manufacturing portland cement. Raw material dryer means an impact dryer, drum dryer, paddle-equipped rapid dryer, air separator, or other equipment used to reduce the moisture content of feed materials. Raw mill means a ball and tube mill, vertical roller mill or other size reduction equipment, that is not part of an in-line kiln/raw mill, used to grind feed to the appropriate size. Moisture may be adde d or removed from the feed during the grinding operation. If the raw mill is used to remove moisture from feed materials, it is also, by definition, a raw material dryer. The raw mill also includes the air separator associated with the raw mill. Rolling average means the average of all one-minute averages over the averaging period. Run average means the average of the one-minute parameter values for a run. TEQ means the international method of expressing toxicity equivalents for dioxins and furans as defined in U.S. EPA, Interim Procedures for Estimating Risks Associated with Exposures to Mixtures of Chlorinated Dibenzo-pdioxins and -dibenzofurans (CDDs and CDFs) and 1989 Update, March 1989.

§60.7(a)(4) Notify the Administrator of planne d changes to the operation or equipment.

§60.7(b) Keep records of the occurr ence and duration of any startup, s hutdown, or malfunction in operation §60.11(c ) The opacity standards set forth in this part sh all apply at all times excep t during periods of startup, shutdown, and malfunction. §60.11(d) At all times, including periods of startup, shutdow n and malfunction, owners and operators shall, to the extent practicable, maintain and operate any affected facility including asso ciated air pollution control equipment in a manner consistent with good air polluti on control practice for minimizing emissions.

§60.8 and §60.675 perform initial compliance testing within 60 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days af ter initial startup and at such other times as may be required by the Administrator under Sec tion 114 of the Clean Air Ac t. Conduct test under such conditions as the Administrator shall specify to the plant operator based on representative performance of the affected facility. Use EPA Method 5 or Method 17 to de termine compliance with the PM standard and use EPA Method 9 to determine complia nce with opacity standard.

• The sample volume shall be at least 1.70 dscm (60 dscf). For Method 5, if the gas stream being sampled is at ambient temperature, the sampling probe and filter ma y be operated without heaters. If the gas stream is above ambient temperature, the sampling probe and filter may be operated at a temperature high enough, but no higher than 121°C (250°F), to prev ent water condensation on the filter.

• For transfer points on belt conveyors and any other a ffected facility, including multiple storage bins with combined stack emissions, the minimum total time of observations shall be 3 hours (30 6-minute averages). The duration may be reduced from 3 hours to 1 hour if there are no individual r eadings greater than the opacity limit and there are no more than 3 readings greater than the opacity limit for the 1-hour period.

• For baghouses that control emissions only form an i ndividual enclosed storage bin, the duration of the Method 9 observations shall be 1 hour (ten 6-minute averages).MDAQMD Federal Operating Permit Riverside Cement Company Permit Number: 1200003

Appendix B, Page 3 • The minimum distance between the observer and the em ission source shall be 4.57 meters (15 feet). The observer shall, when possible, select a position that minimizes interference from other fugitive emission sources (e.g., road dust). The requir ed observer position relative to th e sun (Method 9, Section 2.1) must be followed. For affected facilities using wet dust s uppression for particulate matter control, the spray sometimes generates a visible mist. The water mist mu st not be confused with particulate matter emissions and is not to be considered a visible emission. When a water mist of this nature is present, the observation of emissions is to be made at a point in the plume where the mist is no longer visible.

• A 30-day notice is required prior to th e initial performance test. If, af ter 30 days notice for an initially scheduled performance test, there is a delay in conducting any rescheduled performance test required in this section, the owner or operator of an affected facility shall submit a noti ce to the Administrator at least 7 days prior to any rescheduled performance test.
