Which of the following is NOT a reason to contact the Georgia Environmental Protection Division?

Contacting the Georgia Environmental Protection Division (EPD) is essential for certain regulatory and safety reasons, particularly in relation to wastewater management and environmental health. In this case, increased construction activity in the area does not necessarily warrant contacting the EPD unless it results in specific environmental concerns, such as the discharge of pollutants or impacts on water sources.

On the other hand, projects exceeding 10,000 gallons per day or residential systems over 2,000 gallons per day are significant because they can greatly affect the surrounding environment, necessitating oversight and monitoring to ensure compliance with environmental laws and standards. Additionally, the introduction of new chemical substances in wastewater presents potential risks to public health and the ecosystem, making it critical to inform the EPD to assess and manage any hazardous impacts.

Thus, while increased construction activity may indirectly affect environmental factors, it does not automatically trigger the need for EPD involvement as do the other options, which involve more direct regulatory implications.
