PERMIT BRIEFING MEMO
<br />1. Facility Description
<br />Honeywell International, Inc (Honeywell) engages in the manufacturing of wheels and brakes for
<br />aircraft. The manufacturing of metal wheels and brakes involves grinding, pressing, cutting,
<br />milling, drilling, deburring, etching, anodizing, shot-peening, washing, coating, painting, testing,
<br />and assembly. The manufacture of carbon brakes involves pressure molding, carbon segment
<br />needling, densification, machining, high temperature heat treating, testing, and assembly. Copper
<br />linings were added to the South Bend process in 2021. No wastewater is produced from copper
<br />linings which is the mixing, molding, and pressing copper linings for a variety of assembled parts
<br />Honeywell manufactures. Honeywell also engages in the testing of aircraft fuel controllers and
<br />fuel systems.
<br />The manufacturing facility is spread throughout several major building groups and is
<br />approximately 900,000 square feet. There are four main groups that have operations that occupy
<br />the facility. The Wheels and Brakes Valve Stream (WBVS) uses South Bend as its base of OEM
<br />operations, producing wheels and brakes for Commercial and Military customers. This operation
<br />occupies Plants 3A, 4, 4A, 5, 12, 12A, 17, 21, 25, 35, and the Transportation Building. The main
<br />operation includes a carbon fiber brake component factory and a metal/aluminum machining and
<br />processing factory for structural wheel and brake components. Honeywell’s Engineering Test
<br />Services (ETS) division occupies several Plants 3, 13, 14, 15, 15A, 19, and 32. For the testing of
<br />Wheel and Brake components as well as Fuel Control modules that are designed in South Bend,
<br />but manufactured in Rocky Mount, NC. There are a large number of engineers on site as part of
<br />the mechanical Center of Excellent (MCOE) that reside in Plants 4B, 12, 12A, and 14. Finally,
<br />Ground Support Solutions occupies Plant 26 and is a design, test, and building operation,
<br />dedicated to hardware used to service Honeywell supplied components globally. Automotive is
<br />now vacant, previously occupying plants identified as 1, 7, 9, 10, 23, 28, 31, 34, I-Beam, and 501,
<br />accounting for approximately 422,000 square feet.
<br />Plant operations are, in part, continuous, with approximately 500 employees. Building
<br />construction ranges from 1944 with additions and upgrades through 2007 and operates 24/7 on 3
<br />shifts.
<br />2.Discharge Description
<br />Honeywell has two permitted outfalls: Outfall 002 (407 MRS Wastewater Treatment Plant
<br />System), and Outfall 005 (Zyglo Process).
<br />Outfall 002 - Wastewater Treatment Plant - is located in plant 12A and is used to treat and
<br />discharge batches of wastewater and does not discharge continuously. Wastewater discharged at
<br />this outfall is subject to the Metal Finishing Categorical Pretreatment Standards. Therefore, the
<br />more stringent of limits provided in either 40 CFR 433.15 or Chapter 17 of the City of South Bend
<br />Municipal Code have been applied without modification. Non-categorical wastewater is never
<br />commingled with categorical wastewater prior to discharge.
<br />Discharge from Outfall 002 come from rinse waters from the Local Etch Line (LE) process,
<br />Anodize Line tank dumps and rinse tank dumps, Belt Washer Wastewater, DI backwash, also
<br />called regenerate, Nitric dialysis process, Sulfuric Dialysis Process. The DI units remove
<br />impurities from the rinse waters so that the water may be reused.
<br />NOTE: Honeywell has moved the discharge location of the non-categorical wastewater from the
<br />regeneration of DI Units 1 and 2, to fifty (50) feet to the cast of Outfall #002. This discharge site is
