Does Burlington forbid its disposal in the sewer?
The Burlington sewer use ordinance forbids sending materials to the sewer that:
Flammable (flash point < 141 deg F), reactive or explosive materials;
Liquids having a pH equal to or less than 5.0, or greater than or equal to 9.5 or other corrosive property capable of causing damage to wastewater facilities;
Highly viscous materials (i.e. more viscous than oil) capable of causing an obstruction in the wastewater system;
Materials that have or create a strong odor (including hydrogen sulfide, carbon disulfide, ammonia, trichloroethylene, sulfur dioxide, formaldehyde, chlorine, bromine or pyridine);
- Wastewater capable of significantly raising the temperature of the system;
Grease or oils according to the following
- petroleum > 15 mg/L,
- animal or vegetable > 100 mg/L,
- non-emulsified or "floatable" oils or grease; or
- Pharmaceuticals or endocrine disrupters.
