Statement of Work Wastewater sedimentation tank Sediment Removal

USDA/NCAH

Ames, Iowa

Background The wastewater sedimentation tank located at the south campus of the (NCAH) National Centers for Animal Health is divided into two compartments for settling sediment out of the wastewater from non-infectious animal barns. Animal waste is generated by cattle, horses, sheep, poultry and other species. Wastewater is run through one of the two compartments until the sediment is too dense and the settling tank becomes ineffective. This is determined by testing the solids content of the wastewater downstream from the sedimentation tank. At that point the wastewater is directed through the second compartment.

The requirement of this contract is to clean an individual compartment which contains a high content of solids. The cleaning process shall occur at approximate four month intervals with the following target dates for calendar year 2012. February 28, 2012, June 28, 2012, October 26, 2012.

Each compartment of the sedimentation tank is approximately 8’ wide by 35’ long by 5’ deep at the outflow and inflow. Volume is approximately 10,500 gallons per compartment.

The following scope is intended to be priced as one event.

Scope

A) Mobilization to the USDA/NCAH location at 1800 Dayton Ave., Ames, Iowa 50010 B) Remove non-infectious animal waste material utilizing an industrial vacuum process. Active side of the tank to remain actively flowing at all times during this process.

C) Enter the below grade tank and power wash the interior, ensure that all feathers have been removed from the screens and there is one inch or less of sediment remains in the tank.

D) Collect residual material and cleaning rinsate with a vacuum.

E) Refill tank with clean water following inspection by USDA representative.

A three inch hydrant water connection is available within 80 feet of sediment tank; if you plan to use this source proper backflow prevention will be furnished and employed by the contractor.

F) Once refilled, USDA/NCAH FEU personnel will switch valves to activate clean compartment and make the other compartment inactive.

G) The sediment tanks have been tested, and the Des Moines Metropolitan Wastewater reclamation facility (WRF) has agreed to accept waste to be processed in their anaerobic digester during this event and future events at a rate of $0.1940/gallon plus fees. This rate was directly from the DMWRF website on 1-11-12. This quote was based on the high solids concentration of the material, if the cleaning process adds significant amounts of water the pricing structure may differ. Contractor shall take this into consideration before making a proposal to USDA/NCAH.

H) Transport and offer for disposal all collected liquid, debris, and rinsate to the Des Moines Metropolitan Wastewater Reclamation Facility (DMWRF) located at 3000 Vandalia Rd., Des Moines, Iowa. Arrangements are to be made ahead of time with the following individual; Point of contact is Mr. Larry Hare 515-323-8010.

I) Waste hauler must be licensed with (WRF) J) Document to the USDA the proper decontamination of all reusable equipment. Although the waste material is generated from non-infectious animals, you are expected to decontaminate reusable equipment utilizing industry standards.

K) Provide USDA/NCAH with proper documentation of waste disposal from the WRF.

L) It shall be the responsibility of the contractor to pay Des Moines WRF all costs/fees associated with waste disposal/treatment, to include costs that may be incurred concerning waste testing, etc by the WRF.

M) The DMWRF has stated that they do not require a Non-Hazardous waste statement from the USDA/NCAH. Should a Non-Hazardous waste statement be required by the contractor, the form may be presented to Karla Tebben (USDA/NCAH Environmental Protection Specialist) for completion. Karla.K.Tebben@aphis.usda.gov N) Contractor shall begin work no later than 14 days after receiving the Notice to Proceed.

O) Notify USDA/NCAH facilities engineering unit at least one day prior to starting work at location. (515 337 7260 or 7328) ask for Bruce Johnson.

Safety Plan to be provided before work is started Provide a comprehensive written safety plan including permit required confined space entry plans Provide detailed description of all personal protective equipment to be employed Provide training certificates for employees for all safety procedures being employed and for all equipment operated for this project.

Provide calibration data on air monitoring equipment Provide decontamination procedures to be used for this project Allow three business days for USDA/NCAH industrial hygiene and safety office to review said plans/documents.

Provide latest annual test report for the RPZ backflow, if using USDA/NCAH water source.
