Tampa Bay Fisheries, Inc - Executive Summary |
|
EXECUTIVE SUMMARY Tampa Bay Fisheries Inc. currently operates a Shrimp processing facility in Dover, Florida. This is primarily an agricultural/rural residential area. The site is located immediately north of State Road 574, between Gallagher Road, and Macintosh Road. Commercial properties are located along SR574 and agricultural/rural residential properties are located to the north. Several small residential areas exist to the east and to the west of the site. Two reclaimed phosphate pits (north pond and South pond) are located on the western portion of the site and these are interconnected by a ditch system. Tampa Bay Fisheries processes about 80,000 pounds of raw shrimp per day and produces a shrimp product for wholesale to markets and the restaurant industry. The TBF shrimp processing operation consists of storage, thawing and soaking, peeling, wash down and rolling tanks for product transfer within the facility. Please refer to the bitmap picture included in the Risk Manag ement plan submittal, dated June 1999. Tampa Bay Fisheries uses or stores for use in it's processes, chemicals which are listed as hazardous by the Environmental Protection Agency (EPA). The chemicals reported are 16,000lbs of Ammonia (anhydrous) and 67,000lbs of Propane gas. Ammonia (anhydrous) The quantity of ammonia used requires Program Level 3 reporting. As a result, a Process Hazard Analysis is provided which includes a worst case scenario and an alternative model for hazard assessment. RMP*Comp software was used to estimate the chemical impact. The hazard analysis is based on census and EPA data available through the use of Landview software (US Census and EPA). The population estimate is 8149 persons located within 2 miles of the facility calculated for a worst case scenario and 275 persons within a .20 mile radius for the alternative scenario. The alternative model is based on a less severe and more probable event such as an occurrence of a valve or pipe rupture, takes into account our assumption that the presence of emergency shut down mechanisms and other safety equipment such as ammonia sensors are present and these will shut down the system in the event of severe leakage. Under these conditions, the theoretical maximum loss of 1000lbs of ammonia is used. The calculations are summarized as follows: Propane (liquid) The quantity of propane used requires Program Level 3 reporting. A Process Hazard Analysis is provided which includes a worst case scenario and an alternative model for hazard assessment. RMP*Comp software was used to estimate the chemical impact. The hazard analysis is based on census and EPA data available through the use of Landview software (US Census and EPA). ). The reported population estimate is 175 persons located within .3 miles of the facility calculated for a worst case scenario, and 20 persons within a .10 mile radius for the alternative scenario. The alternative model is based on a less severe and more probab le event such as an occurrence of a valve or pipe rupture which could result in escape of flammable gas. Under these conditions, the theoretical maximum loss of 1000lbs of propane is used. The calculations are summarized as follows: The processes listed herein had no accidental release that caused offsite impacts provided in the risk management program rule (40 CFR 68.10(b)(1)) within the past five years. No additional measures are necessary to prevent offsite impacts from accidental releases, however the plant safety procedures are subject to continual review. The undersigned certifies that, to the best of my knowledge, information, and belief, formed after reasonable inquiry, the information submitted is true, accurate, and complete. _________________________________ _________________________________ Signature Print Name ________________________________ _____________ Title Date Summary of Calculations RMP*Comp Ver. 1.06 Results of Consequence Analysis Chemical: Amm onia (anhydrous) CAS #: 7664-41-7 Category: Toxic Gas Scenario: Worst-case Liquefied by refrigeration Quantity Released: 16000 pounds Release Duration: 10 min Release Rate: 1600 pounds per min Mitigation Measures: NONE Topography: Rural surroundings (terrain generally flat and unobstructed) Toxic Endpoint: 0.14 mg/L; basis: ERPG-2 Estimated Distance to Toxic Endpoint: 2.0 miles (3.2 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) ------------------------------------------------ Population estimates for Worst Case Scenario Ammonia - 2 mile Radius Age 0 Thru 4: 639 Age 05 Thru 09: 620 Age 10 Thru 19: 1298 Age 20 Thru 49: 3833 Age 50 Thru 64: 1053 Age 65 And Over: 706 Aggregate Personal Income: 105267257 American Indian: 26 Asian/Pacific Islander: 60 BLCKGR: Black Population: 137 CNTY: High Owner Cost: 0.0 High Renter Cost: 0.0 Hispanic Population : 1283 Houses built before 1940: 0 LOCATION: 27.991544, -82.236725 Land Area (sq.
