Section 1200-03-16-.56 - WOOL FIBERGLASS INSULATION MANUFACTURING PLANTS(1) Applicability and Designation of Affected Facility (a) The affected facility to which the provisions of this rule apply is each rotary spin wool fiberglass insulation manufacturing line.(b) The owner or operator of any facility under subparagraph (a) of this paragraph that commences construction, modification, or reconstruction after November 6, 1988, is subject to the requirements of this rule.(2) Definitions (a) "Glass pull rate" means the mass of molten glass utilized in the manufacture of wool fiberglass insulation at a single manufacturing line in a specified time period.(b) "Manufacturing line" means the manufacturing equipment comprising the forming section, where molten glass is fiberized and a fiberglass mat is formed; the curing section, where the binder resin in the mat is thermally "set'; and the cooling section, where the mat is cooled.(c) "Rotary spin" means a process used to produce wool fiberglass insulation by forcing molten glass through numerous small orifices in the side wall of a spinner to form continuous glass fibers that are then broken into discrete lengths by high velocity air flow.(d) "Wool fiberglass insulation" means a thermal insulation material composed of glass fibers and made from glass produced or melted at the same facility where the manufacturing line is located.(3) Standard for Particulate Matter (a) On and after the date on which the performance test required to be conducted by 1200-3-16-.01(5) is completed, no owner or operator subject to the provisions of this rule shall cause to be discharged into the atmosphere from any affected facility any gases which contain particulate matter in excess of 5.5 kg/Mg (11.0 lb/ton) of glass pulled.(4) Monitoring of Operations(a) An owner or operator subject to the provisions of this rule who uses a wet scrubbing control device to comply with the mass emission standard shall install, calibrate, maintain, and operate monitoring devices that measure the gas pressure drop across each scrubber and the scrubbing liquid flow rate to each scrubber. The pressure drop monitor is to be certified by its manufacturer to be accurate within ±250 pascals (± 1 inch water gauge) over its operating range, and the flow rate monitor is to be certified by its manufacturer to be accurate within ± 5 percent over its operating range.(b) An owner or operator subject to the provisions of this rule who uses a wet electrostatic precipitator control device to comply with the mass emission standard shall install, calibrate, maintain, and operate monitoring devices that measure the primary and secondary current (amperes) and voltage in each electrical field and the inlet water flow rate. In addition, the owner or operator shall determine the total residue (total solids) content of the water entering the control device once per day using Method 209A, "Total Residue Dried at 103°-105°C," in Standard Methods for the Examination of Water and Wastewater, 15th Edition, 1980. Total residue shall be reported as percent by weight. All monitoring devices required under this subparagraph are to be certified by their manufacturers to be accurate within ± 5 percent over their operating range.(c) All monitoring devices required under this paragraph are to be recalibrated quarterly in accordance with procedures under 1200-3- 16-.01(8)(b).(5) Record Keeping and Reporting Requirements (a) At 30-minute intervals during each 2-hour test run of each performance test of a wet scrubber control device and at least once every 4 hours thereafter, the owner or operator shall record the measurements required by subparagraph (4)(a) of this rule.(b) At 30-minute intervals during each 2-hour test run of each performance test of a wet electrostatic precipitator control device and at least once every 4 hours thereafter, the owner or operator shall record the measurements required by subparagraph (4)(b) of this rule, except that the concentration of total residue in the water shall be recorded once during each performance test and once per day thereafter.(c) Records of the measurements required in subparagraphs (a) and (b) of this paragraph must be retained for at least 2 years.(d) Each owner or operator shall submit written semiannual reports of exceedances of control device operating parameters required to be monitored by subparagraphs (a) and (b) of this paragraph and written documentation of, and a report of corrective maintenance required as a result of, quarterly calibrations of the monitoring devices required in subparagraph (4)(c) of this rule. For the purpose of these reports, exceedances are defined as any monitoring data that are less than 70 percent of the lowest value of each operating parameter recorded during the most recent performance test.(6) Test Methods and Procedures (a) The reference methods contained in subparagraph (5)(g) of rule 1200-3-16-.01 except as provided in subparagraph (5)(b) of rule 1200-3-16-.01, shall be used to determine compliance with paragraph (3) of this rule. Applicable methods are as follows:1. Method 1 for sample and velocity traverses;2. Method 2 for stack gas velocity and volumetric flow rate;3. Method 3 for stack gas dry molecular weight;4. Method 4 for stack gas moisture content; and5. Method 5E for the measurement of particulate emissions.(b) The sampling time for each test run shall be at least 2 hours and the minimum volume of gas sampled shall be 2.55 dscm.(c) The performance test shall be conducted while the product with the highest loss on ignition (LOI) expected to be produced by the affected facility is being manufactured.(d) For each test run, the particulate mass emission rate, R, shall be computed as follows: Click to view Image
Where:
R = mass emission rate (kg/h)
Ct = particulate concentration as determined by Reference Method 5E (mg/dscm)
Qstd = stack gas volumetric flow rate as determined by Reference Method 2 (dscm/min)
(e) The glass pull rate, P, for the manufacturing line shall be computed as follows: Click to view Image
Where:
P = glass pull rate (Mg/h)
Ls = line speed (m/min)
Wm = trimmed mat width (m)
min = minutes
Mg = megagrams
h = hour
g = grams
M = mat gram weight (g/m2)
LOI = loss on ignition (weight percent), as determined by ASTM Standard Test Method D2584-68 (Reapproved 1979), "Ignition Loss of Cured Reinforced Resins"

For each 2-hour test run, the average glass pull rate shall be computed from at least three glass pull rates determined at intervals of at least 30 minutes during the test run.

E = mass emission level (kg/Mg)
R = mass emission rate (kg/h)
Pavg = average glass pull rate (Mg/h)
