22. What legal standard should apply? The choice of a legal standard can determine: Who pays for remediation? Who pays for remediation? Whenever possible, we want it to be the case that The polluter pays. Whenever possible, we want it to be the case that The polluter pays. What level of precaution will be chosen by waste handlers and other possible hazardous waste sources? What level of precaution will be chosen by waste handlers and other possible hazardous waste sources? Waste handlers will choose a higher level of precaution if that reduces the risk of a lawsuit later. Waste handlers will choose a higher level of precaution if that reduces the risk of a lawsuit later. Therefore the threat of legal action can provide significant incentives. Therefore the threat of legal action can provide significant incentives.

23. Possible standards: Negligence standard: Negligence standard: Waste handler has a duty to exercise due care. Waste handler has a duty to exercise due care. If it can be proved that damages were caused by the waste handlers negligence (or lack of due care), then the waste handler can be forced to pay compensation. If it can be proved that damages were caused by the waste handlers negligence (or lack of due care), then the waste handler can be forced to pay compensation. An example: One rule thats sometimes applied in the courts is that the defendant is guilty of negligence if An example: One rule thats sometimes applied in the courts is that the defendant is guilty of negligence if (damages) × (probability of contamination) > cost of preventing contamination What legal standard should apply?
