The States May 13, 2020 SIP
submittal also updates requirements for gasoline transport trucks, bulk terminals, and service stations;
establishes a storage tank control threshold in lieu of the current systemwide control strategy; strengthens storage tank monitoring requirements;
aligns related recordkeeping and reporting; and adds RACT requirements for major sources of VOC and/or NOx in the 8- hour Ozone Control Area. The submittal also includes clarifying revisions and typographical, grammatical and formatting corrections throughout Reg. 7. We propose to approve the revisions to Reg. 7 included in Colorados May 13, 2020 submittal as identified in Table 5. Below, we describe in detail Colorados proposed revisions and the basis for our proposed approval of them. Additional analysis on how revisions meet RACT

requirements can be found in the TSD
for this action.
a. Part A
The revisions add a new Part A
heading, encompassing Sections I and II. Part A contains applicability and general provisions for Reg. 7. The revisions also include renumbering and updates to Parts and Sections referenced throughout Part A. The revisions do not change the substance of SIP approved rules. We therefore propose approval of the changes to Part A.
b. Part B
The revisions add a new Part B
heading for Sections I, II, III, IV, V, VI, VII previously Reg. 7, Sections III
through XV. and appendixes B and C.
Part B regulates the storage, transfer, and disposal of VOC and petroleum liquids and petroleum processing and refining. The revisions to Reg. 7, Part B, Sections IV and VII update the gasoline

Section IV previously Section VI
regulates the storage and transfer of petroleum liquid, and Section VII

Revisions to Sections IV and VII and the removal of the former Appendix E update requirements for gasoline transport trucks, bulk terminals, and service stations to align with current federal requirements for gasoline transport truck testing and vapor control systems. Section IV.A.2.j.
adds a new definition for vapor collection system. The definition is clear, straightforward, accurate, and
