Nonhazardous Anti-Corrosive Odor Control Chemicals for collection system
SECTION 1.0: SCOPE
1.1. The purpose of this program is to reduce hydrogen sulfide H2S and other odor-producing agents at established control points at the least cost to the Town of Orangetown. SECTION 2.0: BACKGROUND
2.1 In the past The Orangetown Wastewater Treatment Plant used Bioxide (Calcium Nitrate) that was manufactured by Siemens-US Filter to control odors downstream of the Hunt Road, Nyack and RPC Pump Stations. This non-hazardous nitrate-based chemical was delivered to storage tanks at Hunt Road and Nyack Pump Stations and the chemical was injected by chemical feed pumps at the headwork. The annual Bioxide usage was 55,000 gallons. The Bioxide quantities is solely stated for informational purposes to the Bidder. The Town currently uses GG220, sold by the G&G Enterprises, Inc, at various locations in the collection system to reduce odors downstream of the injection points. GG220 has been delivered as a part of an agreement between the Town and G&G Enterprises who has been able to meet all aspects of the existing contract. The current contract holder has also provided to the Town manhole insert carbon filters to aid in the removal of H2S as a value-added service at no additional cost. The Contract expires after the 2023 season and the Town is seeking alternatives to compare effective means of odor removal that may provide the same or better results at the most economical rate.
SECTION 3.0: INTENT
3.1 The intent of this technical specification is to establish a term contract to control hydrogen sulfide and other odor-producing agents utilizing a non-hazardous anti-corrosive chemical on a seasonal basis (May 1 through October 31) and “as needed” at the following locations.
PUMP STATION
Nyack Pump Station—1 Spear Street, Nyack, NY—2 MGD
Hunt Road Pump Station—159 Hunt Road, Orangeburg, NY—3.4 MGD
RPC Pump Station—140 Old Orangeburg Road, Bldg. 68, Orangeburg, NY—0.2 MGD

“Rail Trail”—Piermont, NY—currently aided by a carbon filter where the Nyack Gravity Line meets the Siphon line
3.2 Depending on chemical properties, the Bidder may choose to utilize our storage tanks at Hunt Road and Nyack Pump Station but the Bidder is responsible for setting up a chemical delivery system at all pump stations. The Bidder may also inject the chemical at a location outside a pump station as long as the location chosen will not interfere with traffic and is within town property. All costs associated with an alternate delivery system including any hoses, tanks, pump connectors controls, appurtenances, etc. shall be the responsibility of the successful BIDDER and shall be included in the price bid for this contract. A detailed description of the proposed alternate non-hazardous, anti-corrosive chemical delivery system shall be submitted as part of this bid. The Town will consider the use of an initial method that pre-cleans the system prior to the delivery of the Non-Hazardous, Non-Corrosive chemical if the Bidder is able to demonstrate that the use of the pre-cleaning method will not damage the system and will result in a more efficient and effective use of the long-term maintenance chemical. All proposals that include this additional methodology must be submitted as a detailed description of the method, the proposed cost, and the expected benefits of using the method.
