Question: Gina McCarthy presided over the dedication ceremony for the Regional Renewable Energy Procurement Project, what was her role with the United States Environmental Protection Agency?
Context: A Renewable Identification Number (or RIN) is a serial number assigned to a batch of biofuel for the purpose of tracking its production, use, and trading as required by the United States Environmental Protection Agency's Renewable Fuel Standard (RFS) implemented according to the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007. The Uranium Mill Tailings Radiation Control Act (1978) is a United States environmental law that amended the Atomic Energy Act of 1954 and authorized the Environmental Protection Agency to establish health and environmental standards for the stabilization, restoration, and disposal of uranium mill waste.  Title 1 of the Act required the EPA to set environmental protection standards consistent with the Resource Conservation and Recovery Act, including groundwater protection limits; the Department of Energy to implement EPA standards and provide perpetual care for some sites; and the Nuclear Regulatory Commission to review cleanups and license sites to states or the DOE for perpetual care.  Title 1 established a uranium mill remedial action program jointly funded by the federal government and the state.  Title 1 of the Act also designated 22 inactive uranium mill sites for remediation, resulting in the containment of 40 million cubic yards of low-level radioactive material in UMTRCA Title 1 holding cells. Renewable energy in Costa Rica supplied about 98,1% of the energy output for the entire nation in 2016.  In 2014, 99% of its electrical energy was derived from renewable energy sources, about 80% of which from hydroelectric power.  For the first 75 days of 2015, 100% of its electrical energy was derived from renewable energy sources and in mid 2016 that feat was accomplished for 110 consecutive days despite suboptimal weather conditions.  As a country, Costa Rica has a geographic advantage over others in that its high concentration per capita of rivers, dams, and volcanoes allow for a high renewable energy output.  In addition, Costa Rica is the fourth highest nation in terms of rainfall per capita: it receives an average of 2,926mm of precipitation per year.  As a smaller nation with a population of only 5 million and no major industry, the need for strong energy infrastructure is less than for larger countries of higher population density.  The 1948 elimination of the military of Costa Rica freed up millions of dollars from the government defense budget which are now invested in social programs and renewable energy generation.  As president of Costa Rica in 1948, José Figueres announced that the nation's former military budget would be refocused specifically in healthcare, education, and environmental protection. Regina McCarthy (born May 3, 1954) is an American public administrator and an environmental health and air quality expert, and former administrator for the United States Environmental Protection Agency. This is a list of Superfund sites in West Virginia designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.  The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contamination.  These locations are known as Superfund sites, and are placed on the National Priorities List (NPL).  The NPL guides the Environmental Protection Agency in "determining which sites warrant further investigation" for environmental remediation.  As of March 26, 2010, there were 9 Superfund sites on the National Priorities List in West Virginia.  No additional sites are currently proposed for entry on the list.  Two sites have been cleaned up and removed from the list. Renewable Energy Certificates (RECs), also known as Green tags, Renewable Energy Credits, Renewable Electricity Certificates, or Tradable Renewable Certificates (TRCs), are tradable, non-tangible energy commodities in the United States that represent proof that 1 megawatt-hour (MWh) of electricity was generated from an eligible renewable energy resource (renewable electricity) and was fed into the shared system of power lines which transport energy.  Solar renewable energy certificates (SRECs) are RECs that are specifically generated by solar energy.  Renewable Energy Certificates provide a mechanism for the purchase of renewable energy that is added to and pulled from the electrical grid. The United States Environmental Protection Agency's Green Power Partnership is a voluntary program that supports the organizational procurement of green power by offering expert advice, technical support, tools and resources.  Green Power Partnership provides public health and environmental benefits by expanding U.S. renewable energy markets through the voluntary use of green power. Sackett v. United States Environmental Protection Agency, 566 U.S. ___ (2012) , is a United States Supreme Court case in which the Court held that the Clean Water Act is subject to the Administrative Procedure Act, which requires an appeals process for any ruling by a federal agency.  The Court ruled that the availability of immediate judicial review of compliance orders issued by the United States Environmental Protection Agency is required. The Regional Renewable Energy Procurement Project is an energy project in the San Francisco Bay Area, set to develop 186 sites that will generate a total of 31 megawatts, enough electricity for more than 6,000 residences.  The project is expected to create more than 800 jobs.  In May 2015, Gina McCarthy, head of the federal Environmental Protection Agency, presided over a dedication ceremony at the first designated site for the project, at the location of Hayward's former landfill, next to the Hayward Regional Shoreline. The Republic of Kazakhstan has enormous renewable energy potential, particularly from wind and small hydropower plants.  The country has the potential to generate 10 times as much power as it currently needsfrom wind energy alone.  But renewable energy accounts for just 0.6 percent of all power installations.  Of that, 95 percent comes from small hydropower projects. <ref name="http://www.eurasia.undp.org/"> </ref> The main barriers to investment in renewable energy are relatively high financing costs and an absence of uniform feed-in tariffs for electricity from renewable sources.  The amount and duration of renewable energy feed-in tariffs are separately evaluated for each project, based on feasibility studies and project-specific generation costs.  Power from wind, solar, biomass and water up to 35 MW, plus geothermal sources, are eligible for the tariff and transmission companies are required to purchase the energy of renewable energy producers.  An amendmentthat introduces and clarifies technology-specific tariffs is now being prepared.  It is expected to be adoptedby Parliament by the end of 2014.  In addition, the World Bank’s Ease of Doing Business indicator shows the country to be relatively investor-friendly, ranking it in 10th position for investor protection.
