On May 7, the American Petroleum Institute (API) submitted comments to the Environmental Protection Agency (EPA) on the proposed Tier 3 regulations. API said the agency set up the current comment period around the announcement of recent public hearings rather than the proposal of the regulation which has yet to be published in the Federal Register. The Institute requested the EPA establish a 90 day comment period following the publishing of the rule; it also asked the agency to release the data, analysis methodology, and policy considerations used to formulate the rule.
