Chemical Plants in Deer Park

The plain version

The plants along the Houston Ship Channel are not a backdrop in Deer Park — they carry a large part of the city's revenue, its job base, and its emergency-planning map. What they may emit is decided by the state, through TCEQ permits. How they pay the city is decided by the industrial district agreements the City Council negotiates — payments made in lieu of regular city property tax. How the town prepares for an incident runs through the Local Emergency Planning Committee. Three different rooms, three different levels of government, all pointed at the same fenceline.

This page gathers who permits the plants, who taxes them and on what terms, and who plans for the days something goes wrong — plus the meetings where those decisions actually get made. Same promise as the rest of this hub: where we put a number on the page, we name the document it came from. A figure that can't carry its source doesn't get published here.

By the numbers

Major air-permitted facilities, Deer Park-addressed
13 operating.
EPA ECHO air-facility search (Major Emissions; Active/Operating), per the method and exclusions documented on the Air Quality page.
Who sets what they may emit
The Texas Commission on Environmental Quality issues the air permits (state authority, not the city).
TCEQ air-permitting authority.
How the complex reaches the city budget — mostly off the tax roll
The refinery-and-petrochem complex pays the city largely through in-lieu industrial-district payments, not property tax. The Deer Park refinery alone carries only about $3.5M / 24 ac on the City's ad valorem roll, while roughly $437M / 979 ac sits in the industrial district and pays via PILOT.
HCAD CAMA 2025 roll (Noticed values, dated 2026-08-02), jurisdiction codes 054 = City of Deer Park and 954/984 = Deer Park Industrial District; by CLR calculation.
What that PILOT is worth
FY2025 in-lieu payments of $14,884,571 — about 65% of full taxation (the City states 63%).
