Executive Summary 
 
 
1.    Accidental Release Prevention and Emergency Response Policies 
DPC Enterprises (DPCE) is strongly committed to employee, public and environmental safety.   
This commitment is demonstrated by our comprehensive accidental release prevention program  
that covers areas such as design, installation, operating procedures, maintenance, and employee  
training associated with the processes at our facility.  It is our policy to comply with all  
applicable federal, state, and local regulations as well as implement appropriate controls to  
prevent possible releases of regulated substances.  Unforeseeably, if such a release does occur,  
our highly trained emergency response personnel are at hand to control and mitigate the effects  
of the release. 
 
Our emergency response program includes procedures for notification of the local fire  
department; notification of any potentially affected neighbors; and notification of local, state and  
federal agencies.   Safety is an essential  
part of our operations, the safety devices built-in to the  
design of this facility, the safe handling procedures that we use, and the extensive training of our  
personnel. 
 
2.    The Stationary Source and the Regulated Substances Handled 
DPCE is a 52-year-old company whose primary activities encompass distributing and  
repackaging inorganic chemicals and compressed gases as well as manufacturing water treatment  
products. For example, chlorine is used to produce sodium hypochlorite commonly know as  
household bleach.   We are headquartered in Houston, Texas and operate more than 20 plants  
across the United States. 
 
We have these regulated substances at our facility: Chlorine, and Sulfur Dioxide (anhydrous).   
DPCE transfers and/or stores these materials in 150-lb. cylinders, and ton containers for use by  
our customers. 
 
The maximum inventories of these substances at this facility are: 
 
Chlorine  - 450,000 lbs. 
Sulfur dioxide (anhydrous)  25,000 lbs. 
 
3.    The Worst Case Release Scenari 
o(s) and the Alternative Release  
Scenario(s), including administrative controls and mitigation measures to  
limit the distances for each reported scenario 
 
To perform the required offsite consequence analysis for our facility, we have used EPA's RMP  
Guidance for Wastewater Treatment Plants Reference Tables or Equations.  The following  
paragraphs provide details of the chosen scenarios. 
 
Executive Summary 
 
 
The worst case release scenario submitted for Program 3 toxic substances as a class involves a  
catastrophic release from Chlorine repackaging.  The scenario involves releasing the entire  
contents of a railcar in a gaseous form over 10 minutes.  This release would reach the toxic  
endpoint (0.0087 mg/l or 3 ppm) and public receptors. 
 
One alternative release scenario has been submitted for each toxic substance present in Program  
3 processes. 
 
The alternative release scenario for Chlorine is the failure of a = hose on the filling station in  
the repackaging process.  This would  
release material in a gaseous form over 15 minutes.  It is  
assumed to be controlled by active mitigation measures that include emergency shutdown  
systems. This release would reach the toxic endpoint (0.0087 mg/l or 3 ppm) and public  
receptors. 
 
The alternative release scenario for Sulfur dioxide (anhydrous) is a vessel leak.  This would  
release material in a gaseous form over 15 minutes.  No active mitigation systems were assumed.  
This release would reach the toxic endpoint (0.0078 mg/l or 3 ppm) and public receptors. 
 
4.    The General Accidental Release Prevention Program and the Chemical- 
Specific Prevention Steps 
Our facility has taken all the necessary steps to comply with the accidental release prevention  
requirements set out under 40 CFR part 68 of the EPA.  A number of processes at our facility are  
subject to the OSHA PSM standard under 29 CFR 1910.119.  Our facility is also subject to  
EPCRA Section 302 notification requirements.    The following sections briefly describe  
the  
elements of the release prevention program that is in place at our stationary source. 
 
Process Safety Information 
DPCE maintains a detailed record of safety information that describes the chemical hazards,  
operating parameters and equipment designs associated with all processes. 
 
Process Hazard Analysis 
Our facility conducts comprehensive studies to ensure that hazards associated with our processes  
are identified and controlled efficiently.  The methodology used to carry out these analyses is the  
What if/Checklist (combined).  The studies are undertaken by a team of qualified personnel with  
expertise in engineering and process operations and are revalidated every 5 years as required or  
as necessary.  Any findings related to the hazard analysis are addressed in a timely manner.  
 
 
Executive Summary 
 
 
Operating Procedures 
For the purposes of safely conducting activities within our covered processes, DPCE maintains  
written operating procedures.  These procedures address various 
modes of operation such as  
initial startup, normal operations, temporary operations, emergency shutdown, emergency  
operations, and normal shutdown.  The information is regularly reviewed and is readily  
accessible to operators involved in the processes. 
 
Training 
DPCE has a comprehensive training program in place to ensure that employees who are  
operating processes are competent in the operating procedures associated with these processes.   
Refresher training is provided at least every 3 years and more frequently as needed. 
 
Mechanical Integrity 
DPCE carries out highly documented maintenance checks on process equipment to ensure proper  
operations.  Process equipment examined by these checks includes among others; pressure  
vessels, storage tanks, piping systems, relief and vent systems, emergency shutdown systems,  
controls and pumps.  Qualified personnel carry out maintenance operations with previous  
training in maintenance practices.  Furthermore, these personnel are offered sp 
ecialized training  
as needed.  Any equipment deficiencies identified by the maintenance checks are corrected in a  
safe and timely manner. 
 
Management of Change 
Written procedures are in place at DPCE to manage changes in process chemicals, technology,  
equipment and procedures.  Process operators, maintenance personnel or any other employee  
whose job tasks are affected by a modification in process conditions are promptly made aware of  
and offered training to deal with the modification. 
 
Pre-startup Reviews 
Pre-start up safety reviews related to new processes and to modifications in established processes  
are conducted as a regular practice at DPCE.  These reviews are conducted to confirm that  
construction, equipment, operating and maintenance procedures are suitable for safe startup prior  
to placing equipment into operation. 
 
Compliance Audits 
DPCE conducts audits on a regular basis to determine whether the provisions set out under the  
RMP rule are being implemented.  These audi 
ts are carried out at least every 3 years and any  
corrective actions required as a result of the audits are undertaken in a safe and prompt manner. 
 
Executive Summary 
 
 
Incident Investigation 
DPCE promptly investigates any incident that has resulted in, or could reasonably result in a  
catastrophic release of a regulated substance.  These investigations are undertaken to identify the  
situation leading to the incident as well as any corrective actions to prevent the release from  
reoccurring.  All reports are retained for a minimum of 5 years. 
 
Employee Participation 
DPCE truly believes that process safety management and accident prevention is a team effort.   
Company employees are strongly encouraged to express their views concerning accident  
prevention issues and to recommend improvements.  In addition, our employees have access to  
all information created as part of the facilitys implementation of the RMP rule, including  
information resulting from process hazard analyses in part 
icular. 
 
Contractors 
On occasion, our company hires contractors to conduct specialized maintenance and construction  
activities.  Prior to selecting a contractor, a thorough evaluation of safety performance of the  
contractor is carried out.  DPCE has a strict policy of informing the contractors of known  
potential hazards related the contractors work and the processes.  Contractors are also informed  
of all the procedures for emergency response should an accidental release of a regulated  
substance occur. 
 
5.    Five-year Accident History 
DPCE has had an excellent record of preventing accidental releases over the last 5 years.  Due to  
our stringent release prevention policies, there have been no accidental releases during this  
period. 
 
6.    Emergency Response Plan 
DPCE carries a written emergency response plan to deal with accidental releases of hazardous  
materials.  The plan includes all aspects of emergency response including adequate first aid and  
medical treatment, evacuations, no 
tification of local emergency response agencies and the  
public, as well as post-incident decontamination of affected areas. 
 
To ensure proper functioning, our emergency response equipment is regularly inspected and  
serviced.  In addition, the plan is promptly updated to reflect any pertinent changes taking place  
within our processes that would require a modified emergency response. 
 
The Hillsborough County LEPC is the Local Emergency Planning Committee (LEPC) with  
which our emergency plan has been coordinated and verified.
