August 28, 2014 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to extend the Clean Air Act's (CAA) prohibition against the sale of conventional gasoline in reformulated gasoline (RFG) areas to the southern Maine counties of York, Cumberland, Sagadahoc, Androscoggin, Kennebec, Knox, and Lincoln. This proposal is based on a request from the Governor of the State of Maine for areas within the ozone transport region established under the CAA. The CAA does not give the EPA discretion to deny a Governor's request on this matter. The scope of the EPA's discretion is limited to establishing the date that the prohibition commences. Consistent with the Governor's request, the EPA proposes that this prohibition commence on May 1, 2015 for all refiners, importers, and distributors in the Maine counties referenced in the Governor's request, and on June 1, 2015 for all retailers and wholesale purchaser-consumers in those counties. The EPA is also adding in its RFG opt-out rules a provision to reflect that there is a four- year minimum opt-in period for areas that opt into the RFG program on the basis of their location within the ozone transport region. This clarification will align the federal regulation for RFG opt-out requirements with the CAA.

We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by reports that the pintle pins installed on a certain number of airplanes may be incorrectly protected against corrosion. This AD requires replacing certain pintle pins on the left- and right-hand main landing gear (MLG) with a serviceable part. We are issuing this AD to detect and correct pintle pins that have been incorrectly corrosion-protected, which could cause the pintle pins to shear under normal load and lead to the collapse of the MLG during take-off or landing.

We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by reports of ``BLEED 1(2) LEAK'' messages displayed on the engine indication and crew alert system (EICAS), and indirect damage to components of the electrical wiring interconnection system (EWIS) in the engine pylon area. This AD requires inspecting the EWIS components for damage, and repair if necessary. This AD also requires installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. We are issuing this AD to prevent indirect damage to EWIS components near the engine bleed air pre-coolers, which could result in a dual engine roll back to idle and consequent dual engine power loss and reduced controllability of the airplane.
