Facility Description
Lockheed Martin Missiles and Fire Control Santa Barbara Focalplane (LMC) fabricates and assembles infrared components and imaging systems with an emphasis on Indium Antimonide Focal Plane Arrays in linear and large staring formats. Production consists of placing components on a circuit board, soldering, wet-chemistry processing and cleaning. Finished assemblies are sprayed with a clear, encapsulating conformal coating. Circuit boards are heat-treated in a curing oven before and after coating applications.

Location
The LMC facility is comprised of two buildings at 336 and 346 Bollay Drive in Goleta. The facility is located in the Santa Barbara Business Park and is immediately surrounded by similar commercial and light industrial facilities.

Description of Processes Emitting Toxic Emissions
Reactive Organic Compound (ROC)- and toxic-emitting processes include wipe cleaning, the application of adhesives, sealants and coatings, and the application and stripping of photoresist materials that are used during various steps of the manufacturing process.  Laser welding is also conducted at the facility. In addition, LMC operates five stacked Raypak boilers, each with a rated capacity less than 2.0 MMBtu/hr, and a 284-bhp diesel-fired internal combustion engine.

Health Risk Assessment Results
Cancer risk and non-cancer Hazard Index (HI) risk values were calculated and compared to significance thresholds adopted by the District’s Board of Directors. The District’s Health Risk Assessment Report is available here. The calculated risk values and applicable thresholds are as follows (with significant risks shown in bold):

* The risk footprints (isopleths) show the point of maximum impact (PMI), maximally exposed individual resident (MEIR), maximally exposed individual worker (MEIW) and closest sensitive receptor.
**No isopleths were plotted for the 8-hour chronic non-cancer risk as there were no calculated 8-hour chronic non-cancer HIs above 0.1.

Based on these results, the operations at LMC in 2018 did not present a significant cancer or chronic non-cancer risk to the surrounding community. However, there was a significant acute non-cancer risk on two public roadways immediately adjacent to LMC. This risk has been reduced below the District’s significance risk threshold as described below in the Risk Reduction section.

Risk Driving Toxic Emissions
Nickel, emitted from laser welders and combustion equipment, is the primary driver for the acute non-cancer risk and 8-hour chronic non-cancer risk. The primary cancer risk and chronic non-cancer driver pollutant at the point of maximum impact (PMI) is arsenic, which is emitted by combustion equipment and laser welders. LMC’s entire Facility Emissions Summary for 2018 is available here.

Public Notification
The 2018 operations at LMC created a significant acute non-cancer risk on two public roadways immediately adjacent to LMC. Because there are no residents, businesses, or property owners to notify, an online public notification is being conducted in lieu of the traditional mailing. The public notification page for LMC’s 2018 HRA is located here.

Risk Reduction
Because this facility’s health risk assessment indicates a significant risk, the facility operator was required to conduct an airborne toxic risk reduction audit and develop a plan to implement airborne toxic risk reduction measures. LMC submitted their Risk Reduction Audit and Plan (RRAP) in March 2025, which is available here. The District conditionally approved the RRAP on June 17, 2025. The District’s conditional approval letter is available here. The following measures are enforceable elements of the RRAP:

1. Measure 1 – Permanently Remove Unitek Laser Welder. LMC will permanently remove the Unitek laser welder from their operating permit. The RRAP notes that this laser welder has been out of service since 2022.
2. Measure 2 – Install Controls on Amada Laser Welder. LMC installed a fume extractor on the Amada laser welder on September 16, 2024. This fume extractor contains a pre-filter, a HEPA filter, and a high capacity gas-filter, with a 5.5 pound carbon capacity. The HEPA removal efficiency is 99.97 percent at 0.3 µm. LMC will submit a permit application for the operation of the fume extractor.
3. Measure 3 – Future Laser Welders Require Controls. Installation of a fume extractor is required for any future laser welders. LMC shall submit a permit application and receive a final permit prior to installation of any new laser welders.

The reduction of toxic air pollutant emissions was begun in 2022 with removing the Unitek Laser Welder from service. The installation of the fume extractor on the Amada Laser Welder in September 2024 fully reduced the acute non-cancer risk below the District’s significance risk thresholds.
