Deer Park Community Advisory Council

Deer Park Community Advisory Council (DPCAC) builds a true partnership between Houston Ship Channel  industry and community in Deer Park, Texas  At meetings held 9-10 times a year, we provide a forum for candid conversation about industry-related issues of community interest or concern.

Open, honest dialogue makes plant members aware of what the community expects of them.  It helps community members understand what plants do and how they work.

The primary issues we address are environment, safety, health, security, emergency response and communications, and hazardous materials transportation.  We also discuss other quality of life issues like the economy and education.

DPCAC currently has 28 community members plus several Deer Park High School student members. They include individuals who live, work or attend school in Deer Park, and representatives of organizations and government entities serving Deer Park. 

Twenty plant members represent 15 industrial facilities in Deer Park, including chemical plants, a refinery, storage terminals, hazardous waste management firms, and related facilities. See DPCAC Plant Directory.

DPCAC celebrated its 25th Anniversary in March 2015.  Historical highlights were documented in a 25th Anniversary History booklet.

"Question of the Month" 

Q. What is underground injection of hazardous aqueous waste in deepwells?

A. Underground injection of hazardous waste is a widely used management method for hazardous waste disposal. “Deepwell” use is governed by EPA and State regulations as well as stringent permitting, design, and operational requirements.  The EPA instituted the Underground Injection Control (UIC) program for the purpose of protecting Underground Sources of Drinking Water (USDW). Additional regulations were added to injection wells that injected hazardous waste. They include what is commonly known as a “10,000 year No Migration Petition.”  These permits are very strict in terms of the geologic criteria where injection can occur. Only geology that confines the injection between impermeable layers like shale is allowable.  Injection wells are designed with concrete and steel casing to protect any potential underground water sources. A separate annulus between the casing and the injection pipe is filled with fluid which is kept at a higher pressure so that, even in the event of a leak, the injection fluid will be injected.  (#3 -- May 2016 – Texas Molecular)
