TRRP Training: 2022 Program

presented by: GSI Environmetal Inc.

Texas Risk Reduction Program regulations (TRRP; 30 TAC 350) establish consistent risk-based protocols for assessment and response to soil, groundwater, or surface water impacts associated with environmental releases of regulated wastes or substances.

Presented by GSI Environmental Inc., this popular and informative training series is a must for professionals who need a working understanding of TRRP and those needing to stay up-to-date with the latest TCEQ TRRP guidance and policies.

TRRP Training Course (2 Days): Provides an overview of the TRRP framework and step-by-step training on property assessment and response action procedures established under the TRRP rule

Attendees will become acquainted with rules, key guidance and policies covering affected property assessments, protective concentration levels, and response actions. The course material presents strategies for efficient project management in compliance with TRRP and explains the various report forms adopted by TCEQ.

Abstract
The reaction between atomic oxygen and amidogen radical, NH2, has bee studied at 295 K by infrared kinetic spectroscopy. The NH2 radical was produced by excimer laser photolysis of NH3 at 193 nm and reacted with O atoms produced by a microwave discharge of dilute O2/He mixtures. IR transient absorptions of NH2, and of NH and OH radicals formed as reaction intermediates, were monitored using a tunable infrared color-center laser. The room-temperature rate constant for the overall reaction was measured as (6.5 ± 1.3) X 10-11 cm3 molecule-1 s-1. The minor channel leading to NH + OH was observed but accounted for at most about 8% of the NH2 reacting. The rate constant for the reaction NH + O was determined from fitting the NH time profile to be (6.6 ± 1.5) X 10-11 cm3 molecule-1 s-1.
