The California Air Resources Board just voted to regulate shipboard emissions again - just several months after an earlier attempt was struck down by the Ninth Circuit Court of Appeals. The proposed rules and the Board's "authority" to enact such rules are available here.
Some quick problems:
Board Is Regulating Beyond California territory:
“Regulated California Waters” means all of the following (A) all California internal waters; (B) all California estuarine waters; (C) all California ports, roadsteads, and terminal facilities (collectively “ports”); (D) all waters within 3 nautical miles of the California baseline, starting at the California-Oregon border and ending at the California-Mexico border at the Pacific Ocean, inclusive; (E) all waters within 12 nautical miles of the California baseline, starting at the California-Oregon border and ending at the California-Mexico border at the Pacific Ocean, inclusive; (F) all waters within 24 nautical miles of the California baseline, starting at the California-Oregon border to 34.43 degrees North, 121.12 degrees West, inclusive; and (G) all waters within the area, not including any islands, between the California baseline and a line starting at 34.43 degrees North, 121.12 degrees West; thence to 33.50 degrees North, 118.58 degrees West; thence to 32.65 degrees North, 117.81 degrees West; and ending at the California-Mexico border at the Pacific Ocean, inclusive. Legal Authority - Air Resources Board's aggressive reading of the Supremacy Clause
Under State and federal law, the Air Resources Board (ARB or Board) can regulate both criteria pollutant and toxic diesel PM emissions from marine vessels. State law authorizes ARB to regulate marine vessels to the extent such regulation is not preempted by federal law. The proposed regulation is not preempted under the Ports and Waterways Safety Act (PWSA), and it does not conflict with the implementing U.S. Coast Guard regulations. Federal authorization under the Clean Air Act (CAA) is required for regulating new marine engines and for requiring retrofits on existing engines. However, no CAA authorization is required for implementing in-use operational requirements on existing marine vessel engines, such as the in-use emission limits in the proposed regulation. As a nondiscriminatory regulation with substantial benefits, the proposed regulation does not violate the Commerce Clause. And federal and state cases support ARB’s authority to regulate both U.S. and foreign-flag vessels within “California Coastal Waters.”
This issue and State's attempts to regulate in traditionally federal areas is the subject of an amicus brief we filed in the UFO Chuting v. Smith case (original post is here, Ninth Circuit opinion is here, cert petition is here), presently pending review of UFO's petition for a writ of certiorari at the U.S. Supreme Court.
As we pointed out to the Supreme Court, (quoting our brief) even within their waters (baseline to 3 nautical miles seaward) states do not possess "police power" under the Submerged Lands Act to regulate navigation:
The Act limits the ability of the states to enact regulations which interfere with commerce, navigation, defense, and international affairs. While states were granted regulatory powers over the submerged lands, and waters above those lands from the coast line to three nautical miles seaward, the Act expressly provides that federal law regulating interstate commerce and navigation is “paramount” to any state’s attempts to concurrently regulate these resources. The Act provides:
The United States retains all its . . . powers of regulation and control of said lands and navigable waters for the constitutional purposes of commerce, navigation, national defense, and international affairs, all of which shall be paramount to, but shall not be deemed to include, proprietary rights of ownership, or the rights of management, administration, leasing, use, and development of the lands and natural resources which are specifically recognized, confirmed, established, and vested in and assigned to the respective States.
43 U.S.C. § 1314(a) (2000) (emphasis added).
Lots to digest here, I imagine Pacific Marine Shipping Association has a complaint drafted for a federal court lawsuit already.
