In an effort to continue providing intelligent environmental and business solutions for Trinity clients in the upcoming year, we are expanding our ambient field study services to better investigate and remediate odor issues throughout Texas. Personnel in Austin and Dallas are experienced in the use of the Nasal Ranger® Field Olfactometer, odor sampling methods, odor footprint dispersion modeling, and other techniques necessary to successfully identify and mitigate odor concerns at industrial sites.
The olfactory system plays a major role in the body's natural defense system. Odor can elicit emotional responses and cause a variety of indirect health effects including headaches, nausea and vomiting. Because of this strong response, odor is one of the leading complaints received by environmental regulatory agencies. The Texas Commission on Environmental Quality (TCEQ) is required to respond to all complaints, including odor. Industries most likely to receive odor complaints include chemical and general manufacturing, wastewater treatment, composting operations, and food product manufacturing.
Evaluation of odor impacts stems from odor complaints, local ordinances, and/or state regulations. The Texas Clean Air Act requires agencies to conduct air permit reviews and ensure that facilities are not harming human health or property, and TCEQ has specific Effects Screening Levels and thresholds for odorous chemicals.
Furthermore, one of the major issues associated with odor is nuisance complaints. According to the TCEQ, odor nuisance generally occurs when short-term emissions from a source are of character, duration, intensity, and frequency to
- “be injurious to or adversely affect human health, welfare, animal life, vegetation, or property”
- “interfere with normal use and enjoyment of animal life, vegetation, or property.”
Employees in Trinity's Austin Office are pre-screened, certified assessors who are trained in conducting ambient field studies in response to odor complaints and in accordance with TCEQ's evaluation methodology. Our office is happy to help you respond to odor complaints, assess the impacts odors from your process may have on the surrounding community, and explore odor mitigation options.
