The emission testing group at ORTECH is one of the largest and most experienced teams in Canada conducting compliance stack emission testing, continuous emission monitor relative accuracy test audits, and independent performance verification of emission control equipment. ORTECH has conducted many compliance emission tests with direct involvement from the MOECC.  A positive relationship has been developed over the past twenty-five with the MOECC.  ORTECH believes the MOECC Technology Standards Section, Standards Development Branch would provide very positive feedback on ORTECH’s capabilities, experience, quality of work, resources, etc. in conducting stack testing programs.


Ambient Air Monitoring

ORTECH has the experience, expertise and resources to design, implement and operate cost effective ambient air quality monitoring programs from small fence line studies to large air shed monitoring networks.  ORTECH, on behalf of the Sarnia Lambton Environmental Association (SLEA), has designed, operated and maintained a comprehensive ambient air monitoring network in Sarnia-Lambton since the 1950’s to monitor emissions from the regions vast petrochemical operations.


Odour Assessments 

ORTECH has been helping clients resolve odour issues for over 30 years.  We can sample, test, report on, and testify about Odours including procedures for the collection of odour samples, evaluation of these samples using an olfactometer and community odour surveys. ORTECH routinely conducts point source emission testing programs for all types of sectors including rendering plants, sewage treatment plants, composting facilities, paint spray operations and the food processing industry. For these programs, a number of odour sampling procedures are available for use depending on the characteristics of the point source emissions such as the gas temperature, the presence of moisture in the gases and the expected odour concentration.


Analytical Laboratory Services

ORTECH operates analytical chemistry laboratories which specialize in the analysis of fuel gases for heating value components as well as contaminants which may affect the transmission and combustion of these fuels as well as analysis of sulphur and hydrocarbon compounds. ORTECH also has extensive water quality monitoring and analysis experience.  Our laboratories also specializes in the detailed analysis of reduced sulfur compounds in samples from various industrial facilities where they may be responsible for odour complaints and in fuel gas samples where they may be added as odorants. Other analyses which are conducted include fixed gases, permanent gases and higher boiling point hydrocarbons.  ORTECH also offers analytical services for a wide range of ambient air quality parameters utilizing methodologies that are accepted by regulatory agencies.


Due Diligence/Peer Review

Increasingly complex scientific and technical environmental studies are relied upon by regulatory agencies to make important decisions relating to development, land use, and permitting. Accordingly, it is of critical importance for stakeholders to have confidence in the accuracy and completeness these reports. An ORTECH Peer review brings our 50 plus years of experience to the table to help.
