Facility Description and History
UTC developed, manufactured and tested space and missile propulsion systems
from 1959 to 2004. Production of solid propellant ceased in August 2003. All DTSC has not scheduled a public
other manufacturing operations ended in December 2004. As part of the hearing at this time, but will take
operations, UTC stored and treated hazardous waste generated from the requests into consideration.
manufacturing process before sending the waste off-site to another permitted
facility for further treatment.
The draft Permit applies to five hazardous waste management units as follows:
• Surface Impoundment 0250 stored liquid wastes resulting from metal finishing. Operations ceased in 1983.
• Surface Impoundment 0635 stored liquid wastes resulting from polymer production. Operations ceased in
1983.
HEARING IMPAIRED INDIVIDUALS may use the California Relay Service at 1-800-855-7100 or 711 (TTY).
• Surface Impoundment 0706 stored liquid wastes resulting from solvents and ammonium perchlorate used
for container washing. Operations ceased in 1985.
Surface impoundments 0250, 0635, and 0706 operated under a hazardous waste facility permit issued September 26,
1983 and expired on September 26, 1988. DTSC acknowledged these former surface impoundments as closed with
hazardous waste left in place on November 25, 1991.
• The former Hydrolysis Treatment Facility Station (HTF)
The HTF began operation in September 1997 under a RCRA Permit for the purpose of treating excess
propellant and propellant-related wastes. The permit expired in 2007. UTC notified DTSC of their intent to
close on December 14, 2004. Full demolition and removal of the HTF was completed in July 2008. DTSC
acknowledged the HTF as closed with hazardous waste left in place on May 14, 2015.
• The former Open Burning Facility (OBF)
The former OBF comprises approximately 18 acres and consisted of 10 former open burn units constructed
in 1984. Propellant waste was transported to the OBF and ignited. The residual waste was shipped to a
permitted Class I disposal facility. The OBF operated under interim status. The final burn was on October
18, 1996. DTSC acknowledged the OBF as closed with hazardous waste left in place on March 12, 2015.
Permitting History
UTC first applied for a Post Closure permit on February 27, 2004 for Former Surface Impoundments 0250, 0635,
and 0706. The Post Closure Permit specified the groundwater monitoring requirements and cleanup goals for the
surface impoundments. The Post Closure Permit was approved on December 4, 2006 and expired on December 2,
2016.
On December 18, 2014, UTC applied for a Class 3 permit modification to change the boundary lines of the property.
The western buffer area was sampled and no contamination was found. DTSC approved the Class 3 permit
modification on May 4, 2015 which transferred the western portion of the property, which historically served as the
buffer zone, to the Santa Clara Open Space Authority for use as a natural preserve area.
Federal and state law allows facilities with expired permits to continue to operate if the facility has submitted an
application for renewal that is accepted by DTSC in advance of the permit expiration date. UTC submitted the
required Application to renew and add the OBF and HTF to the Post-Closure Permit in June 2015.
Compliance History
DTSC inspects UTC on a regular basis to ensure compliance with California laws, regulations, and the permit
conditions. For the past 4 years, there have been no violations found at the site.
Post-Closure Permit Renewal Process
The Facility must submit an application for renewal to DTSC. After reviewing the application, DTSC proposes a
permit determination by either preparing a draft permit or proposing a permit denial. UTC submitted an application
for renewal and DTSC required additional information until the application was complete. DTSC prepared a draft
Permit which is available for public review. If there is significant public interest, DTSC will hold a public hearing.
HEARING IMPAIRED INDIVIDUALS may use the California Relay Service at 1-800-855-7100 or 711 (TTY).California Environmental Quality Act (CEQA)
Under the California Environmental Quality Act (CEQA), DTSC must evaluate whether the Permit may have any
significant impacts on human health and the environment. As part of this evaluation, DTSC has proposed a Notice
of Exemption (NOE) which concludes that approval of the draft Permit would not result in any impact to human
health and the environment.
Next Steps
DTSC encourages public participation in our decision-making process and invites the public to review and comment
on the draft Permit. Before making a final determination on the draft Permit, DTSC will review and respond in writing
to all public comments. A Response to Comments document will be sent to all those who submitted comments and
to those who request a copy. A copy of the Response to Comments will also be placed in the information repositories
listed below.
