Municipal bioenergy programs utilize anaerobic digestion to produce renewable energy. These programs provide an avenue for climate positive action in addition to offsetting costs. However, they can also be an unsuspecting source of GHG emissions and a potential safety hazard. FM is the unintended release of biogas; one of the largest sources of GHG emissions from WRRFs. The significance of methane and its impacts on the climate, coupled with burgeoning interest and attention of WRRFs as a source, creates considerable opportunities within the wastewater sector to address both local and global climate action goals by emission reduction. The adoption of LDAR programs can substantially reduce emissions while addressing odors, safety, asset renewal, and other drivers. This presentation will provide an overview of leak detection and repair (LDAR) programs and summarize data collected from optical gas imaging (OGI) fugitive methane (FM) surveys from 15 WRRF over the course of 3 years. A vast majority of WRRFs do not deploy regular LDAR as part of route maintenance. New detection methods developed in the oil and gas sector provides the significant opportunities to implement effective LDAR programs. Leak detection methods include audio, visual, and olfactory (AVO) inspections, portable monitoring instruments, or OGI cameras. The direct appropriation of some of these methods by the wastewater sector may present challenges due high variability and diffuse nature of emissions. However, OGI technology has translated well for its use at WRRFs where it has been effective at detecting biogas leaks and could potentially be a key component of LDAR programs. A Konica Minolta GMP02 OGI camera was used to identify and record methane emissions at solids and liquid treatment processes (Figure 1). Over 200 emissions leaks were classified in three categories of small (1 – 200 ), moderate (201 – 1000) and large (>1000) in g CH4/hr. Quantifications of FM occurred at most locations, but some emissions were qualitatively classified. Example sources of leaks are shown in Figure 2. The outcomes of the survey found that the most common sources of leaks included pressure vacuum release valves (PVRV), floating covers, digester cover safety appurtenances, biogas compressors, biogas condensate and drip traps. At several WRRF, leaks were corrected by plant staff and resurveyed to verify mitigation of the leaks. Additional data summaries will be provided in the presentation and the final proceedings.
