Community Odor Monitoring

Community Odor Monitoring

The objectives of Community Odor Monitoring Projects are to involve the community in assessing odor impacts, determine the odor impacts on nearby residents and provide feedback to operators, stakeholders and community members. A well-executed Community Odor Monitoring Projects helps identify sources of odor pollution and assess the performance of implemented solutions. It also improved factual information and enable proactive response of plant operator to the neighbors’ concerns.

Odor Monitoring for Composting Order of Approval

Odor Monitoring for Composting Order of Approval

Lenz Enterprises has an Order of Approval from the Puget Sound Clean Air Agency. This approval required installation of an odor monitoring system that measures and reports results in odor units (OU)/cubic meter. Lenz installed an Odotech monitoring system, which has electronic noses (e-noses) positioned near the odor sources — one located on the back wall of the ASP zones and the other on the northwest corner of the organics receiving building. Sensor data is automatically logged by the Odotech system and Lenz uses this information to develop reports for the agency.

How to Measure Odor

How to Measure Odor

Odors are normally quantified by dynamic dilution olfactometric analysis. Olfactometric analysis consists of determining the olfactory perception threshold of a gaseous sample. The olfactory perception threshold is defined as the number of dilutions at which 50% of a jury perceives the odor while 50% do not. This does not involve the determination of the quality of the odor. By definition, the olfactory perception threshold is equivalent to 1 odor unit per cubic meter of air: “1 o.u./m3″. The number of dilutions of the odor sample required to obtain 1 o.u./m3 indicates the odor concentration of the sample in odor units per cubic meter of air [o.u./m3].

How to Interpret Odor Nuisance Regulations

How to Interpret Odor Nuisance Regulations

The most common approach to regulating odor impacts is through the interpretation of odor nuisance. The origins of odor nuisance regulations come from English Common Law which balances the rights of individuals. One has the right to swing their arm up to the point that a closed fist approaches another person’s nose. At that point, the other person’s right not to be assaulted prevails.
