To accomplish this mission, we:
Develop and enforce regulations
When Congress writes an environmental law, we implement it by writing regulations. Often, we set national standards that states and tribes enforce through their own regulations. If they fail to meet the national standards, we can help them. We also enforce our regulations, and help companies understand the requirements.
由于人们在日常生活和生产中，使用的杀虫、抗菌、农药等产品越来越多，这些活性剂和装置，会对环境（包括水、土壤、动植物等）产生一定的影响。为了便于更好的管理杀菌、抗菌和杀虫剂等产品，美国EPA制定了联邦杀虫剂，杀菌剂和灭鼠剂法案The Federal Insecticide, Fungicide and Rodenticide Act (FIFRA)。受法案管制的产品包括装置（通过物理原理工作）和活性剂（各种化学成分）。
EPA认证、EPA认证有效期多久？
只要按时续交年费就一直有效。
