1. A. A source which is subject to the provisions of this chapter is also subject to the provisions of any other chapter. However, when this chapter establishes an emission standard for a specific installation which differs from the general emission standard in COMAR 26.11.01—.09, this chapter takes precedence.
2. B. This chapter applies throughout the State. The NSPS requirements under 40 CFR Part 60, Subpart K (effective June 11, 1973), Subpart Ka (effective May 18, 1978), Subpart Kb (effective July 23, 1984), and Subpart XX apply throughout the State.

3. C. Exemptions for Large Storage Tanks.

   1. (1) A welded tank is exempt from the secondary seal requirements of Regulation .03B(2)(a) of this chapter if it contains gasoline or VOC with a TVP less than 4 psia (2.75 kilonewton/square meter) and has a primary seal.
   2. (2) The secondary seal requirements under Regulation .03A(1)(b)(i) of this chapter do not apply if the storage tank is equipped with a liquid mounted seal.
4. D. The provisions of this chapter do not apply to the filling of a motor vehicle's fuel tank.
5. E. If a source becomes subject to any requirement in this chapter because it exceeds a regulation applicability level, the source shall continue to be subject to all applicable requirements, regardless of whether future throughput is below the regulation threshold.
