Should response measures become necessary, training has been given in the proper chain of command for notification. Interstate Chemical Company, Inc. is in direct contact with the Hermitage fire department and is represented in the Mercer County LEPC. The regulated substance handled is; 7 Hydrofluoric Acid 70% CAS# 7664-39-3 Primary Activity; 7 Storage and distribution of 55 gallon drums Use of regulated substance; 7 Distribution and storage Quantities handled/stored; 7 On site storage consists of 10 - 55 gallon drums Worst Case Scenario; Hydrofluoric Acid (70%) is brought into this warehouse in 550 # factory pack drums, no repackaging of this product is performed. With this in mind, it can be assumed that the rupturing of one container will not affect the storage of another container. However, the WCS is developed on the basis that 10 si ngle 550 # (385# per drum, totaling 3850 # HF) drums rupture. Hydrofluoric Acid (70%) Worst Case Scenario was developed on the following assumptions: 1. Maximum one time capacity can be 5500 #'s (various months in 1998). Given a concentration of 70 % HF, the total amount at this time was 3850#'s (5,500*0.7). 2. Maximum storage size is a 550# factory pack there by giving 385 #'s or 37 gallons of HF (550# * 0.70). 3. These 10 - 550# factory packs are to be considered for the WCS. 4. Spill is to last 10 minutes Results of Consequence Analysis Chemical: Hydrofluoric acid 70% CAS #: 7664-39-3 Category: Toxic Liquid Scenario: Worst-case Quantity Released: 3,850 pounds The liquid temperature is below or equal to 77 degrees F (25 degrees C) Mitigation Measures: Release into building with floor area of 75,000 square feet Release Rate to Outside Air: 2.31 pounds per minute Topography: Rural surroundings (open country; few obstacles present) Toxic Endpoint: 0.016 mg/L; basis: ERPG-2 Esti mated Distance to Toxic Endpoint: 0.4 miles (0.6 kilometers) --------Assumptions About This Scenario--------- Wind Speed: 1.5 meters/second (3.4 miles/hour) Stability Class: F Air Temperature: 77 degrees F (25 degrees C) Alternative Scenario Hydrofluoric Acid (70%) Alternative Scenario was developed on the following assumptions: 1. Maximum one time capacity could be 5,500 #'s (various months in 1998). Given a concentration of 70 % HF, the total amount at this time was 3,850 #'s. 2. Maximum storage size is a 550# factory pack there by giving 385 #'s or 37 gallons of HF (550# * .70). 3. This 550# factory pack is to be considered for the ACS. 4. Spill is to last 5 minutes, thereby only 40 gallons total HF is released. Results of Consequence Analysis Chemical: Hydrofluoric acid 70% CAS #: 7664-39-3 Category: Toxic Liquid Scenario: Alternative Quantity Released: 195 pounds Release Duration: 5 minutes Release Rate: 39 pounds per min The liquid temperature is below or equal to 77 d egrees F (25 degrees C) Mitigation Measures: Release into building with floor area of 75000 square feet Release Rate to Outside Air: .0.913 pounds per minute Topography: Rural surroundings (open country; few obstacles present) Toxic Endpoint: 0.016 mg/L; basis: ERPG-2 Estimated Distance to Toxic Endpoint: 0.1 miles (0.2 kilometers) --------Assumptions About This Scenario--------- Wind Speed: 3 meters/second (6.7 miles/hour) Stability Class: D Air Temperature: 77 degrees F (25 degrees C) Interstate Chemical Co., Inc. has utilized the Integrated Contingency Plan (ICP) approach in our preventative measures. We believe the formatting requirements of this approach remains one of the best methods of instituting the most efficient and effective response and prevention measure. This plan is available to both the local fire department and local LEPC. Interstate Chemical Co., Inc. has contracted out any accidental release response measures that might be needed, i.e., cleanup and removal . Interstate Chemical Co., Inc. has had no reportable, nor non-reportable releases within the past 5 years. Plan review will be of an on-going nature conducted by the EH&S department. |
