Installation Description The electric distribution system being privatized is described as follows: Electrical power for Vandenberg AFB is purchased from Pacific Gas and Electric Company (PG&E), and is delivered by two 70-kilovolt (kV) PG&E transmission lines. The PG&E transmission lines enter the Base near the northeast corner and extend in a southwesterly direction to the Base-owned switch station. PG&E ownership terminates at the line-conductor dead-end attachments on the Base-owned switch station structure. The Base owns the electrical distribution system from the connections on the PG&E lines at the switch station to the point of delivery for the end users (facilities served). The AF owned system included in this solicitation consists of overhead 70-kV-rated transmission circuits that feed 12 and 12.47-kV distribution substations. South Base is primarily 12.47 kV. The North Base and Main Cantonment areas are primarily 12 kV. The switch station is a low-profile, outdoor, air-insulated substation consisting of eight 70 kV line terminations (two incoming PG&E-owned lines and six outgoing Base-owned lines) and two 10-megavolt-ampere (MVA) zigzag (grounding) transformers. The transmission-switching equipment provides control and over current protection for six outgoing, Base-owned, 70-kV transmission feeds. The North Loop using circuits NL1 and NL2 supplies Substations B, D, E, and F. The South Loop using circuits SL1 and SL2 supplies Substations C, K, and N. Substation A is radial-fed directly from the switch station through circuits TA1 and TA2. The use of the term loop is primarily for description purposes. Although the Base has the ability to feed from the connecting circuit, the connections between the circuits are normally open and not operated as a loop. The substations incorporate a conventional, outdoor, air-insulated design with either a single- or multi-sectionalized bus arrangement. One, two, or three load-tap changing (LTC) transformers are located in each substation to reduce the 70-kV circuits to 12/12.47-kV circuits terminating at the substation’s metal-clad switchgear. The substation’s metal-clad switchgear provides control and over-current protection for the 12/12.47-kV-rated circuits that exit the substation. The metal-clad switchgear is housed in a masonry-type building that offers protection from the elements and restricts access. •Substation A is located on the Lompoc – Casmalia Road, approximately 0.5 mile north of the Main Gate. This substation serves the main industrial, MFH, and airfield areas. •Substation B is located at New Mexico Avenue and 11th Street. This substation serves the main industrial area and the 7000 Area. •Substation C is located on 13th Street between New Mexico Avenue and State Highway 246. This substation serves the Penitentiary/FCI and the Re-entry Vehicles facilities. •Substation D is located near the intersection of El Rancho Road and Curley Road. This substation serves the northwest portion of the Base, including the 1800 and 1900 Areas. •Substation E is located near the intersection of Bishop Road and Grant Road. This substation serves the northeast portion of the Base, including the 22000 and 23000 Areas. •Substation F is located near the intersection of Ocean View Blvd and Washington Avenue. This substation is under construction as of early 2009 and will provide dedicated service to a new building presently under construction. •Substation K is located on Bear Creek Road near Arguello Boulevard. This substation serves SLC-3. •Substation M is located in Building 727 within SLC-4. It is a 12-kV switch station consisting of circuit breakers configured in a sectionalized duplex-bus arrangement. This substation provides control and over current protection for 12-kV feeders serving SLC-4. •Substation N is located on Coast Road, between SLC-4 and SLC-6. This substation serves as the interconnection between the South Vandenberg Power Plant, Substation M, and the Base electrical distribution system. The 12/12.47-kV distribution system consists of both overhead and underground circuits. The distribution system is based on a three-wire system. At several substations the circuits exit the switchgear via underground ductbanks and transition through riser poles, where they continue as overhead lines. The underground distribution system consists of concrete ductbanks and concrete handholes and manholes that provide access points to the underground conductors. The average burial depth of ductbanks is approximately four feet below ground. The distribution system is constructed primarily in a radial configuration with provisions to interconnect circuits for temporary backfeed and for circuit isolation. Crosstie capabilities are accomplished via gang-operated switches on utility poles and pad-mounted three- or four-way switches as well as crosstie breakers between substations. The South Vandenberg Power Plant (SVPP), which is not included in this solicitation, provides a total of 15 Megawatts (MW) of backup generation capacity. The plant is normally operated in backup mode, except during launch operations at SLC-3 or SLC-4, when it is operated as the prime power source for these two launch facilities. The plant also has the capability to provide a significant portion of the electrical requirements of the Base in either a stand-alone configuration or parallel with the local utility. The plant is not normally run except during launch operations due to several factors including the redundancy/reliability of the utility supply and Base transmission system as well as the economic and environmental constraints of on-site generation. In addition to the two 70-kV transmission lines that terminate at the switch station, PG&E also owns one 115-kV transmission line that traverses the Base in an east–west direction along West Ocean Avenue. This is a public access area in which Santa Barbara County has joint jurisdiction with Vandenberg AFB. Vandenberg AFB is bordered by the Pacific Ocean on its west side. Electrical components such as aerial conductors, transformers, wood poles, and pole-mounted switches located along the coastline show signs of accelerated deterioration (shorter useful life). Corrosion appears to be accelerated by constant exposure to airborne salt and daily fog mists in several locations on Vandenberg AFB. In an attempt to reduce the rate of replacement of system components, the Base has begun the process of using alternate materials of construction that are less susceptible to corrosion, such as stainless steel for transformers, switches, and fused cut-outs in areas that are experiencing shorter useful lives for the metal clad components. Vandenberg SCADA The Base has recently installed a new supervisory control and data acquisition (SCADA) system to operate substations. Remote Terminal Units (RTUs) are located in cabinets at electrical power substations and the switch station. The Master Control Room for the SCADA system is located in Room 107 of Facility 11439, and contains the Central Control Unit, operator’s consoles, mass storage devices, and other required peripheral devices. The system uses a stand-alone fiber loop that extends approximately 44 miles. The SCADA system is included in the solicitation. The SCADA system is not presently connected to the military network and operates as a stand alone system. Approval for access to Room 107 for Contractor personnel shall be coordinated through the Contracting Officer. The Utilities Privatization (UP) Contractor shall provide the Government with ability to monitor the electrical system via read only access to the SCADA system. Geographically Separated Units Vandenberg Village Transmitter Site Located near the eastern military family housing complex, this site covers approximately 442 acres and has one 5,600-square-foot (SF) building. Electrical power is supplied directly from the Vandenberg AFB distribution system via a 12.47 kV feeder originating from Substation C. The system includes a transformer and switchgear, plus overhead and underground distribution network. This feeder also supplies the Lompoc Federal Penitentiary and traverses through that site. Oak Mountain Annex Located near Lompoc, CA, approximately 20 miles from the center of Vandenberg AFB, this site covers approximately 4 acres and has 10 buildings totaling approximately 18,000 SF. Electrical power is supplied directly from a PG&E-owned 12.47 kV line. The system includes transformers plus overhead and underground distribution networks. The natural gas distribution system being privatized is described as follows: Southern California Gas Company (SCGC) supplies odorized natural gas to Vandenberg AFB at three separate delivery point locations. The delivery points are as follows: •One delivery point is located near the North Gate, close to the intersection of State Highway 1 and California Boulevard. This delivery point supplies the Main Base and the north side of the East Housing through separate feeds and pressure regulation and metering equipment. The SCGC supply line for this delivery point is located along State Highway 1. •The second delivery point is located adjacent to Lompoc Road and West Ocean Avenue on South Base. The SCGC supply line for this connection is located along West Ocean Avenue. •The third delivery point supplies natural gas to the Vandenberg AFB Tracking Station located in the middle northern portion of the Base. The Air Force generally owns the natural gas distribution system infrastructure downstream of these delivery points. Main Base The Main Base receives 50 psig natural gas from the SCGC-owned regulator and meter station located near the North Gate (intersection of State Highway 1 and California Boulevard). If required, the Main Base may also be supplied from the South Base natural gas distribution system through a 4-inch steel pipe emanating from South Base and traversing along 13th Street where it interconnects to a Base-owned pressure regulator and metering station located on 13th Street southeast of Facility 6510. The Main Base natural gas infrastructure supplies the privatized West Housing Area through a Base-owned regulator and metering station located north of California Boulevard and west of the North Gate in the vicinity where Ocean View Boulevard (West Housing) ends in a cul-de-sac. With the exception of a few lines that service Base facilities that are located within the West Housing Area, the distribution system infrastructure downstream from this point is owned by the Housing Privatization Contractor (reference contract exhibits between HP Contractor and Air Force for additional information). Natural gas is distributed to service connections on the Main Base through main and service lateral piping of various sizes. Replacement of the original metallic piping with polyethylene (PE) piping began in the 1980s. Replacement continued with a significant project in the mid 1990s that replaced most of the remaining steel piping. Exceptions include relatively small segments that remain steel at 50 psig and the 375 psig, 4-inch steel piping, which interconnects Main Base and South Base. The 375 psig system includes 255 linear feet that is enclosed in a 24-inch steel casing jack and bored beneath Ocean Avenue (which separates Main Base and South Base). The average burial depth of the natural gas piping is three feet. PE pipe was generally installed with warning tape and tracer wires; however, PE piping may have also been installed without tracer wire. It is estimated that 2 percent of the natural gas piping lies beneath 6-inch asphalt pavements on the Main Base. Corrosion protection for the 375 psig steel natural gas piping is provided by a sacrificial anode cathodic protection system installed with the piping in the mid 1990s. The 50-psig steel piping is protected by a combination of impressed current and sacrificial anode cathodic protection systems. Over the years, some areas and facilities served with steel piping have become electrically isolated and are no longer cathodically protected. The extent of these isolated areas is not known. Main Base – Facilities Supplied from within West Housing Area There are facilities located on the Main Base that are supplied natural gas from the West Housing Area natural gas distribution system, which was privatized to the Housing Developer. These facilities include the 14000 Area located west of Utah Road, north of Wyoming Avenue, and south of Juniper Street; the 16100 Area located west and north of Summersill Avenue, east of Utah Road, and south of Montana Avenue; and the Base Chapel (Facility 16200), which is located east of Summersill Avenue and west of Noble Road. Natural gas distribution infrastructure downstream from the points is included in this Utilities Privatization Solicitation with the exception of the old Base Chapel, whose demarcation point with the Housing Developer results in no inventory upstream of standard PODs that can be privatized. In other words, the HP Contractor is required to provide delivery service to the old Chapel. Reference Section J2.12.2.3, Utility System Points of Demarcation, and Table 11. Natural gas is distributed at 40 psig to approximately seven service connections in these areas through approximately 3,800 linear feet of main and service lateral piping that range in size from 1.25 inches to 3 inches. The infrastructure in this area consists of steel piping and valves originally constructed in 1942 and the late 1950s to 1970. The average burial depth of the natural gas piping is 3 feet. It is estimated that 2 percent of the natural gas piping lies beneath 6-inch asphalt pavements in these areas. Corrosion protection for the steel natural gas infrastructure is provided by impressed current cathodic protection systems. East Housing East Housing is supplied from a single delivery point, an SCGC-owned regulator and meter station located near the North Gate (intersection of State Highway 1 and California Boulevard). At this delivery point gas is reduced to 40 psig for delivery throughout the East Housing Area’s northern system (the southern distribution system has been abandoned and is not included in this UP Solicitation). The northern distribution system supplies natural gas to facilities north of Sumac Street and ends in the vicinity of Mulberry Drive and Walnut Street. The housing units in the East Housing area have been demolished to the foundation and the natural gas piping capped at the housing unit slabs. Currently, the East Housing natural gas distribution system supplies natural gas to facilities associated with the Vandenberg Middle School, Los Padres Elementary School, and Martha Negas School; however, the entire natural gas distribution system (mains, sub mains and laterals) up to the housing unit slabs remains active. The Offeror shall propose a Transition Period project to sever the natural gas distribution infrastructure, including removal of aboveground infrastructure and abandonment in place of existing belowground natural gas infrastructure (see 2.10 Specific Transition Requirements). South Base The South Base receives 375 psig natural gas from the SCGC-owned meter station located on South Base on Lompoc Road near West Ocean Avenue. The South Vandenberg Power Plant (SVPP - Facility 525), which is at the southernmost end of the natural gas distribution system, requires natural gas to be distributed at 375 psig. To accommodate other end users the natural gas distribution system utilizes nine district regulator stations to reduce distribution pressure to 50 psig. The district regulator stations provide initial pressure regulation (375 psig to 50 psig) for one facility to multiple facilities served by one district regulator station and the facility-specific service regulators further reduce the pressure from 50 psi to building service pressure. SVPP includes a SCGC-owned metering station to track the consumption of natural gas at that facility. The South Base natural gas distribution system is interconnected with the Main Base natural gas distribution system through a 4-inch steel piping main at the intersection of Arguello Boulevard and Clark Street. From there, piping traverses north onto Main Base along 13th Street, where it interconnects to the Base-owned pressure regulator and metering station located on 13th Street southeast of Facility 6510. Natural gas is distributed at 375 psig on South Base through approximately 55,300 linear feet of steel main piping ranging in size from 0.75 inch to 8 inches. Most of this piping is 8 inches; the other smaller diameter piping supplies the district regulator stations or the South Base/Main Base interconnection piping. The 8-inch 375-psig natural gas distribution system on South Base was originally constructed in 1988 along with sacrificial anode cathodic protection systems. The 4-inch 375-psig piping, valves and the sacrificial anode cathodic protection system that interconnects the South Base and Main Base systems was constructed in the mid 1990s. The average burial depth of the natural gas piping is 3 feet. PE pipe was generally installed with warning tape and tracer wires; however, PE piping may have also been installed without tracer wire. It is estimated that 2 percent of the natural gas piping lies beneath 6-inch asphalt pavements on South Base. A sacrificial anode cathodic protection system and 56 test stations installed with the buried 375-psig steel piping in 1988 provide corrosion protection for the piping. The sacrificial cathodic protection system for this piping is nearing the end of its expected useful life and the aboveground test stations/gas-line markers show signs of severe atmospheric corrosion. Due to the accelerated atmospheric corrosion rate of aboveground steel piping and valves in proximity to the coastline on South Base, Vandenberg AFB has begun replacing the aboveground steel piping and valves associated with the district regulator stations with stainless steel-type construction. Currently, the piping, valves, strainers, and fittings for five of the nine district regulator stations have been replaced with stainless steel-type construction. These include the district regulator stations at or near Facilities 836, 840, 870, and 753 and SLC-4. The pressure regulators and pressure-relief valves at the district regulator stations are constructed with typical component materials (ductile-iron body and aluminum or cast-iron diaphragm cases for the regulators and steel or cast iron for the pressure relief valves) and have not been replaced. The district regulator stations at or near Facilities 848 and 852 and both district regulator stations at SLC-3 are constructed of painted steel piping and valves and similar types of regulators and pressure-relief valves and show signs of corrosion. The 8-inch 375-psig natural gas main piping has limited isolation valves to isolate portions of the system. To conduct repair work on the system the entire 8-inch line has to be isolated and the system purged. This limited ability to isolate the system for repairs could adversely affect equipment supporting the Space Launch Complexes. The Government recognizes this project as an immediate need associated with the system. Vandenberg AFB Tracking Station The Vandenberg AFB Tracking Station natural gas distribution system receives natural gas from the SCGC-owned regulator and meter station located in the middle northern portion of the Base. The natural gas from this delivery point is reduced to 50 psig for delivery to the facilities served. The natural gas distribution system supplies two service connections through approximately 6,800 linear feet of main and service lateral piping ranging in size from 1 inch to 2 inches. The infrastructure in this area was constructed in the 1990s and consists of steel and PE and an impressed current cathodic protection system. The average burial depth of the natural gas piping is 3 feet. It is estimated that 1 percent of the natural gas piping lies beneath 6-inch asphalt pavements. Vandenberg Village Transmitter Site Located near the eastern military family housing complex, this site covers approximately 442 acres and has one 5,600-square-foot (SF) building. This site has no natural gas components. Oak Mountain Annex Located near Lompoc, CA, approximately 20 miles from the center of Vandenberg AFB, this site covers approximately 4 acres and has 10 buildings totaling approximately 18,000 SF. This site has no natural gas components. The water distribution system being privatized is described as follows: The water distribution system at Vandenberg AFB serves the entire Base population, portions of the fire protection system, and the U.S. Lompoc Federal Penitentiary. Vandenberg AFB has two sources of water, the Central Coast Water Authority’s (CCWA) California State Project Water and water from the Base’s wells. The CCWA is intended to be the Base’s primary source of water. The Base’s wells are used to supplement the CCWA source during periods that exceed CCWA supply or when CCWA supply is unavailable. CCWA is not a firm water supply as CCWA supply can be taken out of service for any 30-day period with minimum notice. Water delivered to Vandenberg AFB originates from the California Aqueduct system and is treated by the CCWA in the 43-million-gallon-per-day (MGD) Polonio Pass Water Treatment Plant. The water is transmitted to Vandenberg AFB via a 140-mile pipeline that also serves as a supply line to numerous retail domestic water distributors in San Luis Obispo and Santa Barbara counties. This supply pipeline is known as the Coastal Branch Aqueduct (CBA). The Vandenberg AFB water distribution system connects to the 39-inch CBA near Firefighter Road and State Route 1. The CBA is not a part of the Vandenberg AFB water system, but it does cross the base through an easement granted by the Air Force. The pipeline enters Vandenberg AFB near the town of Casmalia and traverses the Base in a southerly direction, exiting east of the main gate area. A Base pipeline conveys water from the CBA connection to a blending station located at the Base Main Reservoir. During those periods when the Base uses well water to supplement the CCWA water, the well water is treated and blended with CCWA water at the San Antonio Water plant (Plant 2). The San Antonio Water Plant is the Base’s main water treatment facility. At the plant, the water is treated with sodium hypochlorite for disinfection and is stored in a 2-million-gallon (MG) aboveground steel reservoir. From the reservoir, the water is pumped into the two 4-MG underground concrete reservoirs. Additional treatment provided at the reservoir area includes sodium silico-fluoride solution (fluoridation of water), sodium hypochlorite (disinfection), and aqueous ammonia. From the reservoir area, water flows by gravity to the Main Cantonment distribution system and to other areas of the Base through five distribution pump stations and pressure-regulating valves. Additional disinfection treatment is located at the main water reservoirs (Facilities 20211 and 20222) on Firefighter Road, where the incoming state water is analyzed and chloramines levels are boosted. To maintain chloramine levels, Vandenberg AFB also has a remote treatment plant at Facility 700 on South Base for disinfection. Additional treatment also occurs at some of the remote storage tanks. At least one month each year, the CCWA service is not available. During that time, the Base switches to well water. The well water is chlorinated to reduce the need for flushing water from dead-end segments of the line. The CCWA service uses chloramines. As a result, flushing is required throughout the system when switching from one source to another. Currently, a perennial service contract is in place to manage water quality. The contractor monitors water quality at various locations, conducts flushing operations, and produces drinking water quality reports. The UP Contractor will be required to perform these operations. Because of the great size of Vandenberg AFB, the distances between facilities, and the length of pipe runs in the water distribution system, Vandenberg AFB has encountered difficulty in maintaining potable water standards (chlorine residuals). These great distances have made it economically infeasible to loop water mains in the past. Consequently, it is necessary to regularly flush sections of water lines so that water quality standards are maintained. Although this is wasteful of water resources, it is a necessary aspect of the existing configuration. Flushing is also necessary to control nitration and it is necessary to switch once a year from chloramine residual to using a free chlorine residual for at least thirty-days. One week before flushing, coordination and concurrence with the Government is required to assure sufficient water is available and to conserve water. Additional data regarding flushing requirements can be found in the Water Quality Action Plan, available in the technical library. Vandenberg AFB has discussed in the past the possibility of installing automatic flushing devices at approximately 21 various locations on the installation to reduce the need for manual flushing but this project is not presently designed or funded. One elevated tank, the main reservoirs, and the water pump stations provide system pressure. The system water pressure during normal operations ranges from 51 to 114 pounds per square inch (psi) based on fire hydrant flow tests conducted as part of the water distribution model (Source: Basewide Water Distribution Model, Vandenberg AFB, California, Penfield and Smith, 30 August 2006). Water Wells There are four on-Base groundwater wells located on the Main Base, completed in the San Antonio Groundwater Basin, which are used for the groundwater supply. The wells were constructed in the 1960s (Wells 4 and 5, upgraded in 1996), the 1970s (Well 6, upgraded in 1999), and the 1990s (Well 7A). The capacity of these wells ranges from 850 gallons per minute (gpm) to 1,250 gpm. The wells are excluded from this solicitation. The POD is as defined in J3.12.2.3 Utility System Points of Demarcation, Table 11, Unique Points of Demarcation. Water from the wells is treated first at the wellfield by one of two degasifiers, which are included in this solicitation, to remove hydrogen sulfide. Each degasifier provides treatment for two wells. From the degasifiers, the well water gravity flows to the San Antonio Water Plant. Three additional wells, Wells 1, 2, and 3, are not in operation and are not included in this solicitation. These wells are located on South Base and are not interconnected with the potable water system. Pump Stations Vandenberg AFB has one main pump station (Facility 22313) and five distribution pump stations: Canyon Pump Station (Facility 23150), East Housing Pump Station (Facility 30080), North Vandenberg Pump Station (Facility 1991), Tank A Pump Station (Facility 686), and Tank B Pump Station (Facility 621). The capacities of the pump stations range from 10 to 100 horsepower and from 125 to 500 gpm. Each of the five distribution pump stations is equipped with two pumps and no emergency generator. The main pump station (located at the San Antonio Plant), Facility 22313, is equipped with four pumps capable of 1,600 gpm. The five distribution pump stations transfer water between the water distribution mains and the storage tanks. Each of the stations is equipped with automatic controls that operate the pump as needed. There are numerous fire pumps located throughout Vandenberg AFB but they are excluded from this potable water system package. The Air Force will retain ownership and operation and maintenance responsibility for these pumps. Tanks The water-demand requirements for Vandenberg AFB are supported by water tanks and reservoirs that provide operational flexibility during the peak-flow-demand periods, equalize system pressure, and provide emergency storage capacity. The potable distribution system utilizes 15 tanks and reservoirs for storage. The tanks are steel, with the exception of the two 4-MG underground storage tanks that are constructed of concrete. Chemical treatment of Base water occurs at the San Antonio Water Plant (Tank 22313) and the Main Reservoir (Tanks 20221 and 20222), and at remote tanks far removed from the initial storage points, such as Tanks 700 and 462. All the metal tanks currently in use, except for the three small tanks, are reported to be protected with cathodic protection systems. However, the 2004 Tank Inspection Reports reported the cathodic protection system in Tank 22313 was in need of replacement and there were no cathodic protection systems for Tanks 462 and 700. In addition, the condition of the cathodic protection system for Tank 23211 was unknown. The 2005 Cathodic Protection Annual Performance Booklet reported readings below the recommended standards for Tanks 700 and 22313, and no information was available for Tanks 31770 and 23211. The 2006 Cathodic Protection Annual Performance Booklet also reported that the cathodic protection system for Tank 23211 had been repaired. Vandenberg AFB has other water tanks that are not included in this solicitation. Tank 15003 (an elevated steel tank in the Trailer Park) and Tank 1505 (an elevated steel tank in Munitions Area) were disconnected from the water distribution system. Other tanks identified on the system maps and in Real Property records and not specified herein are also not included in this solicitation and are either not connected to distribution system or they only support fire systems. Water Distribution Mains Distribution mains and laterals in the Base water system range in size from 0.75 to 36 inches in diameter. The construction of the Vandenberg AFB water distribution system began in 1940. However, the Base closed in 1946. In the 1950s, the Base was re-activated and the temporary 1940s infrastructure was replaced with a permanent system. The system has periodically been upgraded and expanded to handle increased system demands and to support new missions. As the Base moved from an Army installation to its Ballistic Space and Aeronautical missions during the 1950s to the 1970s, new SLCs were constructed outside the Main Cantonment area and supporting facilities were constructed within and around the cantonment area. The existing water distribution system includes two “backbone” pipelines. These 36-inch backbones, running from the main reservoir facility to the Main Cantonment area, are critical for providing capacity for water transmission and fire-flow demands. The 36-inch pipelines from the two 4-MG storage tanks are interconnected with other smaller mains, forming a gridiron distribution system that serves the Base’s facilities. The water distribution system includes metered and un-metered service connections and several air release structures. There is an 8-inch pipeline connecting North Vandenberg and South Base. The general buried depth of the potable water pipe is in the range of 3 to 5 feet with an average depth of 4 feet. Multiple isolation valves are located throughout the water distribution system to facilitate isolation of water line segments for repairs. Fire hydrants function to provide water for fighting fires and are also used occasionally to flush the potable water system. Cast-iron mains are protected from corrosion with sacrificial cathodic protection systems. Generally, tracer wire or marker tape has been installed with non-metallic pipe during initial installation or replacement projects. Generally, replacement buried water lines may be installed using open-cut trenching techniques. An estimated 2 percent of the distribution system piping is beneath paved surfaces. A corrosion control study of Vandenberg AFB was conducted in June 1980, Corrosion Analysis Report Vandenberg AFB, California, by Air Force Engineering and Services Center. The report indicated that soil resistivity varied throughout the Base. The report stated, “Most soil resistivities were below 10,000 ohm-cm and many dropped below 5,000 ohm per centimeter (ohm-cm), indicating the soil is generally corrosive to buried aluminum, steel and, to some extent, cast iron.” The report characterized the Vandenberg AFBs soils as having a high corrosion risk to metal materials. “Corrosion of underground metal utilities is prevalent at Vandenberg. This is due to very low resistivity soil throughout the base and large amounts of underground metal construction. A majority of earlier underground metal utilities have failed. Exceptions are the cathodically protected steel gas distribution piping and much of the 1940 vintage unprotected cast iron water mains. Corrosion failures on these two utilities are also occurring but not excessively.” Based on the reported information, the soil has a high corrosion potential for unprotected metal piping with gradual effect in cast-iron piping. GSUs Vandenberg Village Transmitter Site Water is supplied by a 2,150 linear feet 1.5-inch line from the Base owned meter at the connection to the Vandenberg Village Community Services District water system to the facility served. The water is supplied by the Vandenberg Village Community Services District water system and the Base is billed for what is used by the transmitter site. Oak Mountain Annex This site has its own well, tank, and water distribution network. The water distribution system serving the Oak Mountain annex facilities is considered a non-potable system. The wastewater collection system being privatized is described as follows: The Vandenberg AFB wastewater collection systems consist of laterals, mains, manholes, cleanouts, lift stations, generators, and holding basins. The wastewater collection system infrastructure, which was constructed predominantly in the 1940s and early 1950s, has periodically been upgraded and expanded. The system being privatized includes trunk, main, and lateral sewer lines, 15 lift stations (11 on the Main Base and 4 on South Base), approximately 651 manholes, one treatment pond, one holding basin, and one package WWTP. Lift stations within buildings, within the housing areas, and within several of the launch sites are maintained by others and are not included in this solicitation. In addition, septic tanks and associated drain fields are not included in this solicitation. The wastewater collected in the Main Base gravity system flows from Vandenberg AFB to the City of Lompoc Regional Wastewater Reclamation Plant (LRWRP) through a sewer main constructed in 1978. The line’s diameter varies from 12 to 24 inches (depending upon the line slope), and includes three siphons. A lined holding pond was also constructed along the line near the Base boundary to temporarily store peak flows from the Base that exceed the capacity of the line or to reduce peak flows to the LRWRP. When the peak flows recede, the wastewater in the pond is drained back into the line to flow to the LRWRP. Wastewater flow is measured with a 14-inch sonic flowmeter owned by LRWRP, installed within a vault, which is located near the Lompoc wastewater treatment plant. The permitted monthly average discharge from Vandenberg AFB to the City of Lompoc is 1.3 million gallons per day (MGD). Since the 1990s, as lines were replaced and new lines added, the replacement piping has been either cured-in-place liners, polyvinyl chloride (PVC) or high-density polyethylene (HDPE) and the new manholes have been constructed of pre-cast concrete. PVC is the preferred material for pipeline replacements. Depth of burial for wastewater collection mains ranges from 4 to approximately 15 feet, with an average of approximately 8 feet. The average depth of buried building service laterals is approximately 6 feet. An estimated 2 percent of the collection piping is beneath paved surfaces. Generally, tracer wire or marker tape has been installed with non-metallic replacement pipe or new construction pipe since the 1990s. The original vitrified clay pipe was not installed with tracer wire or marking tape. Within the Main Base, there are ten wastewater lift stations used in the Base’s collection system, which include lift station (LS) 1450, LS 1618, LS 1628, LS 1755, LS 1758, LS 1978, LS 1987, LS 2526, LS 3250, and LS 9340. LS 1758, LS 1987, and LS 3250 are equipped with emergency generators. LS 1758 is also equipped with an emergency holding basin. LS 1450, LS 1618, LS 1628, LS 1755, LS 1978, and LS 1987 transfer wastewater from a small group of buildings to a septic system. LS 3250 collects wastewater generated near Building 3000, and then pumps it via 6 inch and 4-inch force mains to the Main Base gravity collection system. LS 1758 collects wastewater generated near the Flightline; and pumps it via a 6-inch force main to the Main Base gravity collection system. LS 2526 and LS 9340 collect wastewater from a single facility or small group of facilities and discharge to the Main Base gravity collection system. Lift stations are not monitored by a supervisory control and data acquisition (SCADA) system. South Base South Base is located south of Main Base with West Ocean Avenue dividing the two portions of the Base. South Base consists of four main areas with wastewater collection and treatment infrastructure. The four areas are identified as: South Base Area, SLC-3, SLC-4, and SLC-6. All four areas have independent collection and treatment systems. The South Base Area collection and treatment system is excluded from this solicitation. The collection systems within the actual launch complexes at SLC-3, SLC-4, and SLC-6 are excluded from this solicitation. However, facilities in the vicinity of the launch complexes that are not within the restricted area of the complex but have lift stations pumping to septic tank systems are included. An example is the facilities surrounding SLC-6 that utilize two lift stations to transfer wastewater to the single septic tank serving all facilities at and around SLC-6. GSUs Vandenberg Village Transmitter Site Located near the eastern military family housing complex, this site covers approximately 442 acres and has one 5,600-square-foot (SF) building. Wastewater flows from the building to a medium-size septic tank and drain field. The service line from the building, septic tank, and drain field are not included in this solicitation. Oak Mountain Annex Located near Lompoc, CA, approximately 20 miles from the center of Vandenberg AFB, this site covers approximately 4 acres and has 10 buildings totaling approximately 18,000 SF. Wastewater flows from Annex buildings to a septic tank and drain field. The service lines from the buildings, septic tank, and drain field are not included in this solicitation.
