If an importer has more than two import terminals, may the importer of record elect "per gallon" compliance for some import terminals and "average" compliance for other import terminals, or must all imported RFG be designated consistently?

See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. All RFG must be designated consistently. For each of the RFG parameters, an importer must elect compliance on either a per-gallon basis or an average basis. These elections apply to all of the importer's facilities.

Superfund Sites with Commercial Reuse

Commercial reuse of formerly contaminated properties refers to on site commercial activities related to retail shops, office buildings, restaurants, or other businesses.

Superfund Sites with Residential Reuse

Residential reuse of formerly contaminated properties ranges from apartment buildings and care facilities to single-family homes and town homes, and includes continued use and new use activities at these sites.

Superfund Sites with Public Services Reuse

Public Service reuse of formerly contaminated properties refers to use of all or portion of a site by a local, county, or State governmental agency, or a non-profit organization.

Superfund Sites with Green Space Reuse

Superfund sites being reused as green space encompass a wide range of reuse activities including: agricultural reuse (growing crops, land for livestock); ecological reuse (nature preserves, wetlands); and recreational reuse (golf courses, ballfields).

Webinar Series

SRP hosts a series of free webinars that discuss the different types of reuse that are possible and share how particular Superfund sites have become reuse success stories.

Superfund Redevelopment Partnerships

Organizations that have partnered with EPA to support reuse of Superfund sites include the Academy of Model Aeronautics (AMA), Pollinator Partnership (P2), Rails to Trails Conservancy (RTC), The Trust for Public Land (TPL), and the U.S. Soccer Foundation.

Tax Incentive Programs for Superfund Redevelopment

Tax incentive programs offer either tax credits or tax depreciation in the interest of encouraging the redevelopment of Superfund sites.

Waste Emissions Charge

Through the Waste Emissions Charge (WEC), EPA will impose and collect a charge on methane emissions from oil and gas facilities.

A company wishes to blend RFG containing ethanol with RFG containing an ether, such as MTBE. May this blending occur during the VOC-controlled season? During the non-VOC-controlled season?

See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Under § 80.78(a)(8), and as explained in the answer to Prohibitions Question 1 in the September 26, 1994 Question and Answer Document, RFG may not contain a mixture of ethanol and any other oxygenate during the VOC control season…

In a computer-controlled in-line blending operation, adjustments to blending volumes and other blending parameters are made on an ongoing basis to keep the gasoline being blended on-spec. Normally, these adjustments are made automatically by a computer. However, some aspects of the blending operation must be placed in a manual mode when instrument problems arise. The operator is able to enter values (transfer volumes, blend volumes) in the case of such a manual mode operation. The computer records when manually-entered adjustments are made. Is this acceptable data control to the EPA?

See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. It would seem to be appropriate for the software to indicate when data are manually entered, who entered the data and when it was entered. This information should be recorded with the file for the batch and available for…
