- Description
- This Source Sought (SS) Notice is for information and planning purposes only and shall not be construed as a solicitation or obligation on the part of the Bureau of Reclamation. The purpose of this SS Notice is to identify qualified sources capable of performing the work described herein. As a result of this SS Notice, the Bureau of Reclamation may issue a Request for Proposal (RFP). The US Bureau of Reclamation, Acquisitions Operations Group, Denver, CO is performing market research to determine if there are an adequate number of interested and qualified sources able to provide underwater pulsed pressure generating systems and expertise to control invasive zebra and quagga mussels for field demonstration purposes. Basic salient features of pulsed pressure technologies include an integrated field-deployable system operable at depths down to 200 m and capable of producing short duration pressure pulses with variable magnitude (up to 230 dB re 1 microPa @ 1 m) and frequency (pulse rate) control similar to technology conventionally used for marine seismic surveying. This notice is not a request for proposal and the information presented in this announcement will not obligate the Bureau of Reclamation in any manner. Interested parties should submit capabilities statements including the following information in their response: (a) Business name, address, cage code, socioeconomic classification (i.e. HUBZone and/or 8(a)), and a point of contact; (b) A positive statement of your intention to submit an offer for a solicitation; (c) Evidence of successful application and use of pulsed pressure technologies. The evidence should include: contract numbers, project titles, dollar amounts, points of contacts with telephone numbers, and literature sources. Please do not include more than three past projects; and (d) Include attachments cataloging the company's expertise, personnel resources and financial resources that demonstrate company responsibility and capability to perform required work. All interested parties are encouraged to respond to this notice, by e-mail to telliott@usbr.gov no later than the close of business on July 30, 2013. Your company must have a DUNS number and be registered on-line at the System for Award Management (SAM) website, https://www.sam.gov. You will also be required to provide your small business status information either via the RFP or the On-Line Representations and Certifications (ORCA) also located at the SAM website before an award can be made. Your On-Line registration will cover any/all of your offers to the Federal Government, and only needs updated annually. Background Invasive quagga and zebra mussels are thought to have arrived in the Great Lakes Region of United States from Europe in the 1980s and spread to eastern waterways, rivers, and lakes. Quagga mussels were discovered in Lakes Mead, Mojave, and Havasu on the Colorado River in 2007 and have since heavily infested those water bodies. Mussels spread in numerous ways, mainly by transport of larvae in water currents or by attaching to watercraft that are used in infested waters and then transported to another water body. The continued spread of these mussels represents the potential for significant adverse impacts to operations and maintenance of water storage, water delivery, and hydropower facilities; aquatic ecosystems; and recreational use. Development of proactive measures to provide facilities protection for maintaining reliable water and power delivery in the presence of invasive mussels is a top priority for Reclamation's Research & Development Office. One such measure is the proposed use of pulsed pressure technology to either kill or prevent settlement of larval mussels on submerged hydraulic structures and in piped systems. In general, it is expected that the potential effects of seismic sources on various life stages of invasive mussels can range from behavioral responses affecting settlement to immediate mortality of mussels depending on frequencies and sound pressure levels. Available sources for generating underwater pressure pulses (i.e., hydroacoustic sources) have been developed for various applications including marine seismic surveying and can be broadly categorized as mechanical or electrical technologies, both of which can generate short duration pressure pulses. Mechanical Technologies Two technologies, typically referred to as air guns and water guns, have been widely used for seismic surveying and have recently been identified as having potential applicability for controlling aquatic invasive species. Air guns are typically comprised of a pneumatic chamber that when discharged can produce sound pressure levels (SPLs) on the order of 220-230 dB re 1 microPa @ 1 m. The hydroacoustic energy from air guns is emitted as relatively short duration pulses having spectral characteristics in the range of 10 to 200 Hz; The spectral density for which depends primarily on the size of the air gun and associated air water interactions. However, emission frequencies can also be modified to some degree by changing the volume and pressure of the pneumatic chamber. The discharge from air guns creates a rapidly expanding air bubble following by bubble contraction and collapse. Operating pressures for air guns typically range from about 200-2000 psi with operating volumes ranging from as small as 1 in3 up to 2000 in3. Water guns are similar to air guns, but create sound energy by discharging water using a compressed-air driven piston. The discharge from a water gun is initiated through the motion of the piston forcing water through discharge ports at large velocities. The jets create rapidly expanding vapor cavities followed by rapid collapse resulting in primary and secondary pressure pulses. The expansion-implosion mechanism produces short pulses with relatively broader frequency spectra than are typically observed from air guns. Electrical Technologies Electrical technologies for hydroacoustic generation, also known as sparkers, convert electrical energy to acoustic energy. Plasma sparker systems, as they are sometimes referred to, consist of three primary components including a power supply, capacitor, and submersible electrodes between which a high-voltage electrical arc is generated. The electrical discharge from the sparker rapidly vaporizes water in the vicinity of the arc producing hydroacoustic characteristics similar to those generated by air and water guns. Previous studies have indicated pressure pulses generated by sparkers potentially disrupt feeding behavior of adults and may prevent settlement and growth of veligers.
