AC’CENT Environmental Services, Inc.

ACCENT started 33 years ago.  Danny Brevard, P.G. has been the sole creator and owner of ACCENT since 1985.  In 1988, Danny developed a monthly vapor monitoring system called GAS SYSTEM® which has been successfully helping tankowners since the regulations began in 1989. 

Over one million vapor samples have been collected in those years. 

ACCENT has had over 150 technicians providing various services for the petroleum industry.  We currently work in every major location and city in Texas with our team of licensed and certified professionals.  We continue to donate hundreds of hours through the Texas EnviroMentor Program to help folks in our industry.  Our team offers training and best practice presentations to agencies such as the TCEQ, EPA, LADEQ, OCC, and many others.

Respected by Inspectors and Tankowners for integrity and superior knowledge.

ACCENT is a sole-source provider for school districts, non-retail facilities, cities, counties, small airports and state agencies as well as our terrific convenience store clients and friends. 

GAS SYSTEM® does everything needed for the Non-Retail Tankowner…EVERYTHING. 

Danny’s sons have been part of the ACCENT team for 17 plus years and they know how to do tanks!  In 2012, ACCENT started the “switch” to change everyday operation and control over to them.   It’s been a good decision.  Our clients and friends now have the expertise of not only Danny, but Eric, David and Adam.  The Legacy Continues.

ACCENT changes the rules for the Convenience Store Tankowner. 

ACCENT-US takes care of everything so you don’t have to. 

ACCENT has developed unique products to help our clients and friends.  We own and control our tests methods and equipment, some of it patented and/or proprietary.
