The regulatory agencies and the industries have the responsibility for assessing the environmental impact from the release of air pollutants, and for protecting environment and public health. The simple exemption formula is often used as a criterion for the purpose of screening air pollutants. That is, the exemption formula is used for air quality review and to determine whether a facility applying for and described in a new, modified, or revised air quality plan is exempted from further air quality review. The Bureau of Ocean Energy Management's (BOEM) air quality regulations are used to regulate air emissions and air pollutants released from the oil and gas facilities in the Gulf of Mexico. If a facility is not exempt after completing the air quality review, a refined air quality modeling will be required to regulate the air pollutants. However, at present, the scientific basis for BOEM's exemption formula is not available to the author. Therefore, the purpose of this paper is to provide the theoretical framework and justification for the use of BOEM's exemption formula. In this paper, several exemption formulas have been derived from the Gaussian and non-Gaussian dispersion models; the Gaussian dispersion model is a special case of non-Gaussian dispersion model. The dispersion parameters obtained from the tracer experiments in the Gulf of Mexico are used in the dispersion models. In this paper, the dispersion parameters used in the dispersion models are also derived from the Monin-Obukhov similarity theory. In particular, it has been shown that the total amount of emissions from the facility for each air pollutant calculated using BOEM's exemption formula is conservative.
The operation of offshore oil and gas facilities under BOEM's jurisdiction is required to comply with the BOEM's regulations. BOEM's air quality regulations are used to regulate air emissions and air pollutants released from the oil and gas facilities in the Gulf of Mexico. The exemption formulas have been used by BOEM and other regulatory agencies as a screening tool to regulate air emissions emitted from the oil and gas and other industries. Because of the BOEM's regulatory responsibility, it is important to establish the scientific basis and provide the justification for the exemption formulas. The methodology developed here could also be adopted and used by other regulatory agencies.
监管机构和相关行业有责任评估空气污染物排放对环境的影响，并保护环境和公众健康。简单豁免公式常被用作筛选空气污染物的标准。也就是说，豁免公式用于空气质量审查，以确定申请新的、修改的或修订的空气质量计划中所描述的设施是否可免于进一步的空气质量审查。海洋能源管理局（BOEM）的空气质量法规用于监管墨西哥湾油气设施排放的废气和空气污染物。如果一个设施在完成空气质量审查后未获豁免，则需要进行更精细的空气质量建模以监管空气污染物。然而，目前作者无法获取BOEM豁免公式的科学依据。因此，本文的目的是为BOEM豁免公式的使用提供理论框架和依据。在本文中，从高斯和非高斯扩散模型推导出了几个豁免公式；高斯扩散模型是非高斯扩散模型的一种特殊情况。墨西哥湾示踪剂实验获得的扩散参数被用于扩散模型。在本文中，扩散模型中使用的扩散参数也源自莫宁 - 奥布霍夫相似理论。特别要指出的是，使用BOEM豁免公式计算得出的设施每种空气污染物的排放总量是保守的。
在BOEM管辖下运营的海上油气设施必须遵守BOEM的规定。BOEM的空气质量法规用于监管墨西哥湾油气设施排放的废气和空气污染物。BOEM和其他监管机构已将豁免公式用作一种筛选工具，以监管油气及其他行业排放的废气。鉴于BOEM的监管职责，为豁免公式建立科学依据并提供理由很重要。这里开发的方法也可供其他监管机构采用和使用。
