Company Background

• FEDRC owned by Frontier Oil Corporation

• Fortune 500 Company (#496)

• 7th best performing stock of all companies listed on the New York stock exchange (2005)

• FEDRC employs 400 Frontier personnel and 100 contractors

Company Background

• FEDRC situated on 1,000 acre site, which has been in operation since 1917

• Frontier Oil Corp. purchased El Dorado site in 1999

• Direct access to pipelines from Canada and Cushing, Oklahoma

• FEDRC produces gasoline, diesel fuels, aviation fuels, asphalt, and other petroleum based products

Researched Process

• Reducing Primary Sludge

• Erosion Control in the Tank Farm

• Flow of stormwater through tank farm– Frequency of flow– Connection between channels– Stormwater channel characteristics

Scope of the Project

• Soil Lost: 2500 cubic yards– ERE Maps, Tape Measure– Estimated Dimensions and Volume

• Primary Sludge: 25,000,000 lbs– 1 cubic yard soil weighs 2000 lbs– 1 lb soil creates 5 lbs primary sludge

Scope of the Project

• Yearly Sludge Production: 1,250,000 lbs– 25,000,000 lbs total– 50% of erosion occurred in past 10 years

• 10% of WWTP Sludge in 2005– 2005 WWTP Sludge: 13,540,022 lbs

Recommendations

• Armor Stormwater Channels– Groundcover– Global Fill– Rock

• Protecting Inlets and Outlets

• Procedural Changes

Cost Estimate

• Total Cost: $170,000 - $300,000

– High-Priority Areas ($170,000 - $200,000)– Entire Area ($250,000 - $300,000)

• Soil makes up 95% of this cost

• Cost varies according to material use

Benefits of Erosion Control

• Decreased Primary Sludge Generation

• Improved WWTP Efficiency

• Increased Capacity to Recycle Other Sludge

• Decreased Storage Needs

• Improved Stability of Pipe Rack Foundations

• SWP3 Compliance

Cost Savings

Area of Cost Savings Expected Annual Savings

Storage Container Rental Fees $36,135.00Off-site Disposal of Sludge $140,000.00Stormwater Flume Cleaning $1,500.00Pipe Rack Foundations

WWTP Efficiency

Total Savings: $177,635.00

Project Results

• Payback Period: 1.2 to 1.7 years

• Implement Erosion Control in Steps

• Combine erosion control in the tank farm with other practices

Internship Pros and Cons

• Gained experience in a field of interest

• Worked in environmental department

• Helped narrow my future career desires

• Very complex project working primarily on my own
