本技术更新描述了在表面处理和其他排放产生操作期间用于监测排放的方法和设备，以及用于评估现有控制措施是否足以保护公众、环境和相邻人员，或是否符合联邦、州和地方法规或规定要求的方法和设备。本报告的目的是向用户介绍各种可能适用于监测项目排放的测试方法，并描述每种监测方法提供的信息。用于选择特定监测方法的标准必须根据具体情况确定- 设施所有人或指定人提供的案例依据，但应考虑正在进行的表面处理操作的类型；作业产生粉尘的性质；遏制的类型；工作区与公众的距离；敏感的环境受体；邻近人员；涂层、磨料或其他材料中存在的铅、其他有毒金属或危害的数量；以及其他特定于现场的特征。

This technology update describes methods and equipment used for monitoring emissions during surface preparation and other emission generating operations and to assess whether the controls in place are adequate for protecting the public, the environment, and adjacent personnel or meeting federal, state and local regulations or specified requirements. The intent of this report is to present the user with a variety of methods of testing that may be appropriate for monitoring project emissions, and describe the information provided by each of the monitoring methods. The criteria used for selecting a particular monitoring method must be determined on a case-by-case basis by the facility owner or specifier but should include consideration of the type of surface preparation operation being performed; the dust-producing nature of the operation; the type of containment; proximity of the work area(s) to the public; sensitive environmental receptors; adjacent personnel; the amount of lead, other toxic metal, or hazards present in the coating, abrasive or other materials; and other site-specific characteristics.
