Westlake Expansion Project Westlake Compressor Station Gulf South in the Area Gulf South Pipeline Gulf South Storage Facilities Gulf South Pipeline Company, LP y Gulf South has an extensive interstate natural gas pipeline network that gathers gas from the various basins in Texas and Louisiana and delivers that gas to markets in the Gulf Coast, and southern United States. y Gulf South serves various commercial and industrial customers in the Calcasieu Parish area and local distribution companies, including: Entergy CenterPoint Conoco Phillips CITGO Firestone Westlake Polymers SASOL PPG y Gulf South has approximately 200 employees in Louisiana and 12 in the Lake Charles area who actively monitor and maintain our pipeline system. These employees include construction managers, field technicians, measurement and mechanical analysts, and corrosion specialists. y Gulf South contributes approximately $16 Million annually in taxes to the state of Louisiana, with approximately $200,000 in tax revenue directly attributable to Calcasieu Parish. y Gulf South supports local communities through scholarships, education grants, and other forms of community giving. Our Scholarship program offers a $1,000 scholarship to qualifying students in high schools as well as a $500 grant program for qualifying middle and elementary schools that are located on property where Gulf South operates its pipeline system. There are at least 8 high schools and 20 elementary/middle schools in Louisiana that are part of these programs. Westlake Expansion Project Westlake Compressor Station Quick Project Facts GULF SOUTH y Gulf South operates existing natural gas infrastructure in the Westlake Area. y Compressor stations are routine pipeline facilities. y Gulf South provides natural gas to the local distribution company which provides gas for cooking and heating in homes throughout Calcasieu Parish. y The project will not increase the maximum allowable operating pressure of any of the existing pipelines in the area. COMPRESSOR SITE y The permanent facility footprint will be approximately 10 acres. y Area lighting will be limited to maintenance lighting which shall be low and directed into the station (maximum of 20 foot poles, which will be below the existing tree canopy line). y Operating noise levels will not significantly change from today’s ambient background levels at nearby residences. y The compressor building will be set back at least 2,000 feet in the woods off of Myrtle Springs Road. LOCAL BENEFITS y 2-3 full time positions will be hired to operate the facility. y Over $900,000 annually to Calcasieu Parish in additional tax revenue. y Existing tree canopy will remain undisturbed between Myrtle Springs Road and the new station. y Retention of the existing tree canopy for visual screen and additional sound barrier. y Community giving program including scholarships, grants and charitable contributions to qualifying schools that are located on property where Gulf South operates its pipeline system. y Allows continued expansion of the local industrial base and associated jobs. Westlake Expansion Project Westlake Compressor Station Project Overview y Gulf South is serving growing customer needs by installing a new compressor station at the junction of its existing mainline pipeline and an existing pipeline lateral. y The facilities will provide natural gas to Entergy Louisiana, LLC’s Lake Charles Power Station. y Our project is a necessary and primary element of the Lake Charles Power Station which will provide electricity to the Lake Charles area and the expanded industrial base in the parish. y Our project is a $56 Million capital investment and will generate approximately $900,000 annually in additional tax revenue to Calcasieu Parish, Louisiana. y The new Gulf South facilities will consist of two compressor units with a power rating of about 10,000 horsepower combined, approximately 0.3 miles of new 16-inch diameter natural gas pipeline, a new delivery meter station, and a new receipt meter station on an existing Gulf South facility. y Construction period is planned to commence late 2018 with in-service August 1, 2019. CONSTRUCTION TIMELINE Westlake Expansion Project Westlake Compressor Station Project Overview y Engineering parameters require the compressor station to be sited adjacent to Gulf South’s existing mainline pipeline which will provide the gas supply for the Project. y The location of this station minimizes the need to install additional pipeline, acquire additional right-of-way and limits the project’s overall environmental impact. y The project’s traffic management strategy considers school bus traffic and normal traffic patterns. The plan incorporates restrictions on activities such as selective heavy equipment drop off and work hours. A traffic control officer will be present at key times. Westlake Expansion Project Westlake Compressor Station What is a Compressor Station? y Natural gas transmission compressor stations are engineered, constructed, operated and maintained in accordance with Pipeline and Hazardous Materials Safety Administration (PHMSA) safety standards. y A natural gas compressor station provides the energy to flow natural gas from a receipt point to a delivery location using mechanical energy to compress and move gas. y All natural gas pipeline systems employ compressor stations to help reliably distribute gas to communities, businesses, and industrial infrastructure. y A gas compressor consists of a driver or engine connected to a compressor by a drive shaft. A compressor station may consist of one or more engine and compressor packages. y The Westlake Compressor Station will include two reciprocating engines to drive the gas compressors, similar to the images reflected below, and housed within an acoustically treated building to reduce the sound emitted from the facility. 18 feet 45 feet Westlake Expansion Project Westlake Compressor Station Construction Process y The first phase of construction will be partial clearing of trees and site preparation. y Only a small portion of the property purchased will be cleared of trees. Natural tree and brush growth will be left in place to form a visual barrier. y Foundation installation y Compressor building, piping and associated facilities y Fencing y Restoration Westlake Expansion Project Westlake Compressor Station Environmental Evaluation and Protection y Gulf South is committed to being a good steward of the environment. y During site selection, environmental surveys are completed to identify all environmental features and potential habitats. y Gulf South environmental personnel along with FERC, federal and state agencies will evaluate the following 3 locations for the project. y During construction, Environmental Inspectors will be on site to ensure proper implementation of the environmental protection plans as well as to provide oversight for FERC and state agencies. y At the completion of the project, all right-of-way and temporary workspaces will be restored to original conditions as required by regulatory guidelines. Westlake Expansion Project Westlake Compressor Station State and Federal Permits y Federal Energy Regulatory Commission (FERC) is the lead federal agency that oversees the construction of interstate natural gas pipeline systems and regulates the interstate natural gas industry. y FERC is also the lead federal agency responsible for conducting the environmental review and providing approval to construct the proposed compressor station facilities. y The FERC coordinates with the appropriate local, state, and federal agencies and ensures that required environmental permits are secured before construction may begin. Below is a list of the permits required for the project. y Wetland Section 404 Permit – US Army Corps of Engineers y Louisiana State Historic Preservation Society Concurrence Received - LA Dept. of Cultural Development Division of Historic Preservation y U.S. Fish & Wildlife Service Concurrence Received - Louisiana Ecological Field Office y Air Permit – Louisiana Department of Environmental Quality (LDEQ) y FERC requires construction and environmental inspection with frequent reporting once construction begins. y To receive permission to construct, own and operate this
