Your environmental permit states the waste types and quantities you can accept. Normally you will breach your permit conditions if you accept waste types or quantities beyond those stated in your permit.
This COVID-19 regulatory position statement (RPS) only applies to operators of permitted municipal waste incinerators.
If you follow the conditions in this COVID-19 RPS you can accept and incinerate COVID-19 infectious waste at a municipal waste incinerator without varying your environmental permit.
You must get written agreement from the Environment Agency before you use this COVID-19 RPS.
