What should be done before entering an industrial facility for a pretreatment inspection?

Before entering an industrial facility for a pretreatment inspection, it is essential to collect wastewater samples as a part of the preparation process. This step ensures that the inspector has a baseline understanding of the wastewater characteristics before arriving on-site. Sampling can provide critical data regarding pollutant levels, compliance with regulations, and any potential areas of concern related to the facility's operations.

By obtaining samples beforehand, inspectors can formulate specific questions or areas of focus during the visit, leading to a more effective and efficient inspection. This preparation helps the inspection team to prioritize their observations and assessments based on the initial findings from the samples.

While reviewing site history, meeting with management, and completing necessary training requirements are all important aspects of the inspection process, they support the overall inspection strategy rather than being the primary preparatory action that influences immediate inspection outcomes. Collecting wastewater samples directly impacts the quality and effectiveness of the inspection once it takes place.
