Overall, the Storage Building retains integrity of location, design, setting, materials, workmanship, feeling, and association, despite its movement to a different location within the substation property and modifications to the entrance. The building contributes to the historic character and significance of the Midway Substation and is recommended as a contributing resource to the substation district for its association with BPA’s Master Grid development. The resource does not convey sufficient historic significance to be eligible as an individual historic property. The Midway Substation, part of BPA’s master grid development, was constructed near Vernita in Benton County, Washington, in 1941 to serve the Northwest Electric Company and Washington Water Power Company interchange (BPA 1941:73).
The Midway Substation is a key distribution point to Puget Sound, Hanford and eastern Washington. It is notable for delivering power to the Hanford Atomic Works and as a key element for linking the Bonneville and Grand Coulee dams into a single system (DAHP 2011). The power enabled wartime production of plutonium, thereby facilitating development of the nuclear fission bomb deployed against Nagasaki, Japan in August 1945 (Lally 2009). According to BPA internal data, BPA acquired the Midway Substation site on January 1, 1941. The Washington Department of Archaeology and Historic Preservation (DAHP) determined the Midway Substation eligible for listing in the National Register of Historic Places in 2011 (DAHP 2011).
The Midway Substation, along with the Walla Walla and Spokane (Glenn H. Bell) substations, was designed for quick development to accommodate pressing wartime power needs (Daily Capital Journal 1941). The funds allocated for the Midway Substation’s initial construction were part of a $7 million appropriation for BPA grid system completion (Statesman Journal 1941). By mid-December 1941, defense industry applications for power “jumped to an all-time high,” according to administrator Paul J. Raver. Raver emphasized the “government’s policy of long-time planning to meet future power needs enables us to meet the war emergency. We already have completed or have under construction at Walla Walla, Midway, Spokane and several other points, substation facilities which can be rapidly expanded” (Oregonian 1941a). Alan Yonker of Portland submitted the low bid of $151,788 for construction of the substation’s “operator’s cottages, dormitory and garages” (Oregonian 1941b).
In 1944, BPA had installed 230-kV line terminal facilities at Midway Substation for the Hanford No. 1 and No. 2 transmission lines, and was in the process of constructing a second 230-kV transformer bank (BPA 1944:57). The line was designed to increase stable power transmission to the Portland and Puget Sound areas (Oregonian 1944). In 1951, BPA added a third transmission line between Grand Coulee and the Midway Substation. The new 105-mile “steel tower” line was estimated to cost $4 million and would initially transmit power at 190-kV, with an increase to 250 kV the following year, thereby relieving overload on the two existing lines between Grand Coulee dam and the substation (Idaho Statesman 1951). In 1958, BPA awarded Witzig Construction Company of Corvallis, Oregon, a $74,681 contract to construct 230-kV Priest Rapids terminal additions at Midway Substation. The Bend Bulletin reported that, “Work calls for grading, fencing and surfacing the switchyard addition, excavating for and constructing foundations and erection of multiple deadend structures and equipment.” The Midway Substation additions permitted BPA to integrate power from Priest Rapids dam into the “Northwest power pool” and transmit Priest Rapids power to other northwest utilities (Bend Bulletin 1958).
Physical Description
Storage buildings are found at many BPA substations as part of general operations during all eras of BPA’s development. Constructed circa 1956, the Midway Storage Building (approximately 320sq. ft.) sits on a slab-on-grade concrete foundation and is constructed out of standing-seam metal panels with a flat roof finished with standing-seam metal and a metal ventilator. The primary elevation faces north toward the Switchyard and consists of a single-door opening with a flush-paneled metal door and a rectangular metal louver to the west. The west elevation includes an opening with a flush-paneled hatch door above a projecting metal shelf. The south elevation consists of a metal vent hood and small metal louver. The east elevation is comprised of a single-door opening with a flush-paneled metal door. The interior of the Storage Building includes a finished concrete floor, exposed paneled metal walls and ceiling, caged light fixtures, and a small crane on a steel I-beam. Moderate alterations have occurred since the building’s original construction, according to a field investigation completed June 29, 2017 as well as an analysis of aerial images and historic documentation. Changes that have been made include it being moved from its original location to its existing location circa 1981 (BPA Aerial 1981), the removal of its second roof ventilator and capacitors (date unknown), and the creation of the hatched opening and metal shelf (dates unknown).

Physical Description
BPA used rail transfer carts to carry transformers and other heavy loads on fixed transfer tracks from the switchyard into substation maintenance areas and/or untanking towers (Curran 1998:111). The transfer cart was integral to the transfer track’s function and overall maintenance of switchyard equipment. Originally installed in 1941 as part of the site development, the transfer cart is constructed of steel and has a flat open steel deck. The cart deck rests on wheel rail conveyors that glide on the transfer tracks. The resource was observed during fieldwork with a transformer on it near the untanking tower. Though not previously identified in the MPDF or BPA’s asset database, transfer carts, when located within the substation boundaries, may be evaluated as contributing resources to substation historic districts.
Statement Of Significance
The transfer track retains integrity of location, design, setting, materials, workmanship, feeling, and association. The structure contributes to the historic character and significance of the Midway Substation and is recommended as a contributing resource to the substation district for its association with BPA’s Master Grid development. The resource does not convey sufficient historic significance to be eligible as an individual historic property. The Midway Substation, part of BPA’s master grid development, was constructed near Vernita in Benton County, Washington, in 1941 to serve the Northwest Electric Company and Washington Water Power Company interchange (BPA 1941:73).
Physical Description
Transfer tracks are present in some of BPA’s earlier switchyards and are characterized by steel rails that extend from the location of power transformers to switchyard maintenance areas or untanking towers when present. Historically, transfer tracks were used for transporting power transformers and other equipment on transfer carts for routine maintenance and installation. Originally installed in 1941 as part of the site development, the resource is typical of BPA’s transfer tracks. The structure is embedded in the asphalt and is situated on an east-west axis in the southern half of the switchyard, aligned with the untanking tower. Though not previously identified in the MPDF, the transfer track enriches the visual complexity of the switchyard by contributing to the setting and the complex arrangement of individual elements that functioned collectively within the substation during the period of significance.
Statement Of Significance
The Storage Building retains integrity of location, design, setting, materials, workmanship, feeling, and association, despite modifications to the entrance. The building contributes to the historic character and significance of the Midway Substation and is recommended as a contributing resource to the substation district for its association with BPA’s Master Grid development. The resource does not convey sufficient historic significance to be eligible as an individual historic property.

Physical Description
Storage buildings are found at many BPA substations as part of general operations during all eras of BPA’s development. Constructed circa 1954, the Midway Quonset Hut Storage Building (approximately 1,376 sq. ft.) sits on a slab-on-grade 3’ concrete foundation and is constructed out of corrugated metal with ventilators at the roof ridge and metal paneled elevations. The primary elevation faces east and contains a double-door opening with flush-paneled plywood doors under a horizontal infilled window opening and metal lamp, and flanked by two rectangular infilled window openings. The north and south elevations of the hut lack fenestration. The west elevation includes a single-door opening with a flush-paneled plywood door (BPA 2016). The interior of the Storage Building includes a finished concrete floor, exposed corrugated metal and metal paneled walls, suspended circular light fixtures, and a wood loft (BPA 2016). Minor alterations have occurred since the building’s original construction, according to a field investigation completed June 29, 2017 as well as an analysis of aerial images and historic documentation. Changes that have been made over time include the replacement of the original flush-paneled metal doors with existing plywood doors (date unknown), and the infill of window openings circa 1954 (BPA).
Statement Of Significance
The Untanking Tower retains integrity of location, design, setting, materials, workmanship, feeling, and association and meets the minimum eligibility requirements in the BPA MPDF. The building contributes to the historic character and significance of the Midway Substation and is recommended as both a contributing resource to the substation district, and an individually eligible historic property under Criterion C as an excellent example of a Streamline Moderne-style control house constructed during BPA’s Master Grid development period (1938-1945). The recommended period of significance for the resource is its construction date of 1941. The Midway Substation, part of BPA’s master grid development, was constructed near Vernita in Benton County, Washington, in 1941 to serve the Northwest Electric Company and Washington Water Power Company interchange (BPA 1941:73).
Physical Description
Untanking towers typically contain the mechanical equipment used to “untank” power transformers and oil-immersed equipment, and are used conduct maintenance and repair activities at their respective substations (Curran 1998:99). Built in 1941, the Midway Untanking Tower (approximately 10,146 sq. ft.) sits on a concrete foundation and displays a smooth concrete exterior with features representative of the Streamline Moderne-style, including its flat roof and porthole windows. The building’s flat roof is finished with a single-ply membrane (BPA 2016), and features a parapet with concrete coping with metal flashing, and flood lights.

Statement Of Significance
Overall, the Switchyard retains integrity of location, design, setting, materials, workmanship, feeling, and association. The structure contributes to the historic character and significance of the Midway Substation and is recommended as a contributing resource to the substation district for its association with BPA’s Master Grid development. The resource does not convey sufficient historic significance to be eligible as an individual historic property. The Midway Substation, part of BPA’s master grid development, was constructed near Vernita in Benton County, Washington, in 1941 to serve the Northwest Electric Company and Washington Water Power Company interchange (BPA 1941:73).
Physical Description
Switchyards are, in general the “works” of a substation, and feature a complex arrangement of individual elements that function collectively as a part of the system. Switchyard sites are generally characterized by a vertical superstructure of steel, typically latticework, with conductor, circuit breakers, insulators, transmission towers, and other electrical equipment connect incoming and outgoing transmission lines to a series of grade-mounted transformers, circuit breakers, switches and other equipment. In general, switchyards are “designed to control power flow and transform voltages for distribution (Curran 1998:111),” and then feed low voltage distribution and/or high voltage transmission lines out of the complex.
Originally installed in 1941, the Switchyard is flat, covered with crushed rock, and bounded by a metal chain-link fence (Z-8814) with access to the north. The Switchyard includes three current transformers, three small oil and five gas circuit breakers below a dead-end tower surrounded by buswork, and three large power transformers with adjacent transformer radiators to the south, and a long row of two potential transformers, six current transformers, and six gas and 42 oil circuit breakers under three dead-end towers surrounded by buswork to the north.
The switchyard also includes its original transformer track (Z-0000) with cart, a rectangular metal paneled engine generator building with a low pitched front-gabled roof (Z-554), a horizontal oil tank, six original vertical oil tanks atop a slab-on-grade concrete foundation with short concrete retaining wall, as well as multiple small square-shaped metal storage and oil absorbent sheds and concrete paths throughout.
Moderate alterations to the Switchyard have occurred since its original installation, according to a field investigation completed June 29, 2017 as well as an analysis of aerial images and historic documentation. Changes to the plan include its extension to the east circa 1948 (BPA) and west circa 1964 (BPA Aerial 1964). Other changes to the Switchyard include the addition of two new power transformers circa 1945 and the removal of two by 1958 (BPA Aerial 1958), the installation and removal of capacitor housing in 1949 (BPA) and their removal circa 1964 (BPA Aerial 1964), the construction of the condenser by 1958 and its removal circa 1981 (BPA Aerial 1981), new gas circuit breakers to the south of the transformer circa 2004 (BPA Aerial 2004), and the removal of one of the original four power transformers circa 2009 (BPA Aerial 2009). Gas circuit breakers started to replace original oil circuit breakers starting in 1992 (BPA Aerials 1992-2013).

Statement Of Significance
Properties associated with energy development, specifically the establishment of the BPA Master Grid, are historically significant because of the role such properties have played in the history of the Pacific Northwest (Holstine, 1988; Kramer 2009). Much of the development and industry of Washington State has ties to the history of energy development, particularly that which is associated with Columbia River hydroelectricity and its supporting energy transmission infrastructure.
Championed by Franklin D. Roosevelt, the development of hydroelectricity was undertaken in order to harness this vast and undeveloped resource in the Pacific Northwest region (Holstine, 1988), thought to contain nearly half of all hydroelectric power available to the United States (White, 1995). It was believed that the entire future of the Pacific Northwest was directly linked to, and dependent upon, the development of the Columbia River (Bonneville Power Administration, history).
Roosevelt and the United States Congress approved funding and construction of major hydroelectric development within Washington and Oregon, beginning with Bonneville Dam and Grand Coulee Dam in 1933 (Bonneville Power Administration, history). Not long after the completion of the Bonneville Dam, the Bonneville Project Act, later renamed the Bonneville Power Administration (BPA) (White, 1995), was approved by Congress with the intent to grant the BPA the authority to establish an electrical transmission system for the distribution of hydroelectric power generated by the dams (Holstine, 1988).
Commencement of transmission line construction began in 1938, and with each subsequent transmission line completion, the BPA power grid grew larger, connecting more hydroelectric power with portions of Washington State. This interconnected power grid became known as the BPA Master Grid, and the push for its creation was largely based on concerns for national security (White, 1995). Construction work on BPA lines provided jobs during the Depression, specifically for the Works Progress Administration workers who prepared areas where lines and substations were to be erected (Holstine, 1988).
Later, the electrical generation and transmission of the BPA substations and lines would play a significant and critical role in the United States efforts during World War II (WWII) by providing electricity needed for aluminum and atomic development (Holstine). Beyond opening the region to development and industry, providing jobs during the Great Depression, and enabling atomic development through the provision of electricity, energy development has forever altered our natural and cultural history. It has, in essence, shaped the modern Pacific Northwest.
The Midway Substation was built as part of the BPA Master Grid and was a critical link in connecting the Bonneville and Grand Coulee into a single system (Holstine, 1988). It is as a part of the BPA Master Grid, which was nominated to the NRHP by Holstine in 1987, that the Midway Substation has a great deal of historical significance. Kramer (2009) also attaches significance to such resources, noting the eligibility of those properties associated with the BPA Transmission Network. However, the Midway Substation also has historical significance outside its direct association with the BPA Master Grid. In fact, the Midway Substation played a critical role in plutonium production through provision of electricity to the Hanford Atomic Works, which ultimately enabled the development of the atomic bomb dropped on Nagasaki at the close of WWII (White, 1995). Kramer (2009) suggests that a substation, given that it retains sufficient integrity, may be considered eligible to the NRHP as they constitute a portion of the larger BPA Transmission Network.
As a portion of the BPA Transmission Network, and built as a portion of the original BPA Master Grid, the Midway Substation is a property that has contributed to the broad patterns of national and regional history, carrying with it associations with industry, specifically atomic development during WWII, and federal development of public power in the Pacific Northwest. Given that the Midway Substation does appear to have sufficient integrity to convey its historic significance, it is our recommendation that the Midway Substation is eligible under Criterion A for listing in the NRHP.
Although this recommendation is based largely upon the buildings constructed in 1941, eligibility may be extended to those built at a later date. This recommendation is justified in that the property is part of the inter-related BPA Network and a portion of the cohesive system. Therefore, the Criterion G exception for buildings less than 50 years old is applicable.
Physical Description
The Midway Substation consists of eight separate buildings built between 1941 and 1990. The two primary buildings, constructed in 1941, include the control house and the untanking tower, built from reinforced masonry. Additional buildings include the following: two battery buildings, constructed in 1990; an engine generator building, constructed in 1975; a flammable storage unit, constructed in 1979; an additional storage unit, constructed in 1975; and a shed, constructed in 1985. The control house is a two-story building with a rectangular floor plan, with cast in place reinforced concrete basement walls and wall-footing foundations. The roof of the building is flat, consisting of steel bar joists with a tongue and grove wood deck. The untanking tower appears to be of similar construction with a few notable differences. The building is single story, with a reinforced concrete foundation and painted concrete exterior walls.
