and C.-C, n-paraffins also may be considered for exemption. Other compounds which have been shown to have low reactivity include

lohexanone, ethyl acetate, diethylamine, isobutyl acetate, isopropyl alcohol, methyl benzoate, 2-nitropropane, phenyl acetate and triethylamine. This emission limitation may impose an economic burden upon some paint spray booth installations. If such sources are not major contributors to hydrocarbon pollution levels, they may appropriately be considered for exemption.

4.7 Architectural coatings for buildings. The emission of organic compounds from architectural coatings can be reduced by requiring the use of water-base or other coatings having an organic solvent content of less than 20 percent by volume. The effectiveness of the limitations set forth in $$ 4.6 and 4.7 will vary, depending on the nature and amounts of emissions in an area; a rough estimate based on Los Angeles emission data indicates that application of the limitation would result in a 70 percent reduction in organic solvent emissions. In estimating the effectiveness, it should be assumed that all organic emissions are reactive; use of exempt solvents as substitutes for regulated solvents may be considered 100 percent effective in reducing reactive organic solvent emissions. 5.0 CONTROL OF CARBON MONOXIDE EMISSIONS

The emissions of carbon monoxide can be limited by requiring complete secondary combustion of waste gas generated in such operations as a grey iron cupola, blast furnace, basic oxygen steel furnace, catalyst regeneration of a petroleum cracking system, petroleum quid coker or other petroleum process. 6.0 CONTROL OF NITROGEN OXIDES EMISSIONS

6.1 Fuel burning equipment. The emission of nitrogen oxides, calculated as nitrogen dioxide, from gas-fired fuel burning equipment can be limited to 0.2 pound per million B.t.u. (0.36 gm/109 gm-cal) of heat input. This emission limitation 18 about equivalent to a nitrogen dioxide concentration of 175 p.p.m., by volume, on a dry basis at 3 percent oxygen and represents about a 50 percent reduction in nitrogen oxide emissions from uncontrolled gas-fired equipment.

The emission of nitrogen oxides, calculated as nitrogen dioxide, from oil-fired fuel burning equipment can be limited to 0.30 pound per million B.t.u. (0.54 gm /109 gm-cal) of heat input. This emission limitation is about equivalent to a nitrogen dioxide concentration of 230 p.p.m., by volume, on a dry basis, at 3 percent oxygen and represents about a 50 percent reduction in nitrogen oxide emissions from uncontrolled oilfired fuel burning equipment.

6.2 Nitric acid manufacture. The emission of nitrogen oxides, calculated as nitrogen dioxide, from nitric acid manufacturing plants can be limited to 5.5 pounds per ton (2.8 kg. /metric ton) of 100 percent acid produced. This emission limitation is about

equivalent to a nitrogen dioxide concentre-
tion of 400 p.p.m., by volume.
