AirData - 2023 Point Source Emissions

The annual Oklahoma Point Source Emissions Inventory is a data resource that utilizes emissions data to evaluate emission trends, support air dispersion modeling, aids in development of air quality rules, and air toxics risk assessment. Summaries of annual emissions from all Oklahoma permitted facilities are available to be downloaded as excel spreadsheets. These reports are provided as a basic informational resource for the general public. Facilities registered under a Permit By Rule (PBR) are not required to report emissions inventories every year. If a facility registered under a PBR did not report in a year that they are not required to, the prior reported emission amounts are displayed in that year’s data. Column Headings Additional Notes Heading Description Company_ID The unique identifier assigned to the company by Oklahoma DEQ Company The name of the company Facility_ID The unique identifier assigned to the facility by Oklahoma DEQ Facility The name of the facility SIC The Standard Industrial Classification Code for the facility SIC codes can be found at this site https://www.sec.gov/info/edgar/siccodes.htm County The county in which the facility is located Facility_Address Physical address of the facility City City in which the facility is located State Oklahoma Zip_Code ZIP code for the facility Latitude Latitude of the facility Longitude Longitude of the facility Status The Operating Status of the facility in the year in which the emissions were reported. See right and Year_Emissions_Reported below. Not Yet Built facilities have not begun operations and have no air emissions. Operating facilities are facilities that had any regulated emissions during the year of record. Temporarily Shutdown facilities had no emissions in the year of record, but may have emissions again in the future. Permanently Shutdown facilities are closed with no emissions and would require a new permit to resume operations. SOx_Tons Tons of Sulfur Oxides emitted NOx_Tons Tons of Nitrogen Oxides emitted CO_Tons Tons of Carbon Monoxide emitted PM10_Tons Tons of PM-10 emitted. PM-10 is particulate matter with aerodynamic diameter less than or equal to 10 micrometers PM25_Tons Tons of PM-2.5 emitted. PM-2.5 is particulate matter with aerodynamic diameter less than or equal to 2.5 micrometers. PM 2.5 is a subset of PM 10 HAP_Tons Total emissions of all Hazardous Air Pollutants in tons. See right. One of the compounds on EPA's Hazardous Air Pollutants List, except those that overlap with Toxics. The list of Hazardous Air Pollutants can be found at this site https://www.epa.gov/haps/initial-list-hazardous-air-pollutants-modifications Tox_Tons Total emissions of all air Toxics in tons. See right. Any compound listed in OAC 252:100 Appendix O except those that overlap with HAPs. https://www.deq.ok.gov/wp-content/uploads/deqmainresources/100.pdf HAP_Tox_Tons Total emissions of all pollutants that are both a HAP and an air Toxic in tons. See right. A compound that is both a HAP and is in Appendix O VOC_Total_Tons Tons of Total Volatile Organic Compounds emitted. Other_Tons Tons of emissions of Regulated Air Pollutants that do not fall into another category. Currently, this is ozone and hydrogen sulfide. See right. Regulated Air Pollutants are found in OAC 252:100 Appendix P. https://www.deq.ok.gov/wp-content/uploads/deqmainresources/100.pdf Facility_Classification Major means a facility is a major source. Syn-Min means a facility is a synthetic minor. Min means the facility is a minor source. A facility is a major source if it has the potential to emit at least one of the following: 100 tons or more of a regulated air pollutant, 10 tons or more of a single HAP, or 25 tons or more of all HAPs. Facilities with potential emissions below major source levels will be classified as either Syn-Min or Min based on the type of permit that the facility has. Additionally, Air Curtain Incinerators, large Municipal Solid Waste Landfills, and some sources subject to National Emisions Standards for Hazardous Air Pollutants (NESHAPs) are required to obtain a major source permit even if their emissions are below major source levels (see 40 CFR 60 Subpart XXX, 40 CFR 60 Subpart CCCC, and OAC 252:100-8-3 respectively). For this reason, they are classified as Majors. A facility with a minor or synthetic minor permit will be listed as a Major if the facility's emissions are above the major source threshold in the year of record. Year_Emissions_Reported The year in which the emissions were reported. This should be 2023 for nearly all facilities. For facilities registered under a PBR, that may not have reported, the most recently reported emissions are carried forward until a new inventory is reported. Facilities registered under a PBR must submit an emissions inventory the first year that they register under the PBR then according to EPA's National Emissions Inventory schedule. The schedule for reporting for facilities registered under a PBR can be found in OAC 252:100-5-2.1. https://www.deq.ok.gov/wp-content/uploads/deqmainresources/100.pdf本数据集为俄克拉荷马州年度点源排放清单（Oklahoma Point Source Emissions Inventory），依托排放数据开展排放趋势评估、支撑大气扩散模拟、辅助制定空气质量法规，以及开展空气有毒物质风险评估。俄克拉荷马州所有持证设施的年度排放汇总数据可通过Excel电子表格下载，此类报告作为基础信息资源面向公众开放。 根据按规则许可（Permit By Rule, PBR）登记的设施无需每年提交排放清单。若某PBR登记设施在无需提交的年份未上报，则该年份数据将沿用其此前上报的排放数值。 ## 列标题与补充说明 ### 标题 描述 Company_ID：俄克拉荷马州环境质量部（Oklahoma DEQ）为企业分配的唯一标识符 Company：企业名称 Facility_ID：俄克拉荷马州环境质量部为设施分配的唯一标识符 Facility：设施名称 SIC：设施的标准行业分类代码（Standard Industrial Classification Code），可通过以下网址查询：https://www.sec.gov/info/edgar/siccodes.htm County：设施所在县 Facility_Address：设施实际地址 City：设施所在城市 State：俄克拉荷马州（Oklahoma） Zip_Code：设施邮政编码 Latitude：设施纬度 Longitude：设施经度 Status：设施在排放报告年度的运行状态，详见下文及Year_Emissions_Reported字段说明。其中： - 未建成（Not Yet Built）：设施尚未启动运营，无大气排放； - 运营中（Operating）：设施在报告年度内产生合规排放； - 临时停运（Temporarily Shutdown）：设施在报告年度内无排放，但未来可能恢复排放； - 永久停运（Permanently Shutdown）：设施已关闭且无排放，若需恢复运营需重新申领许可。 SOx_Tons：排放的二氧化硫（Sulfur Oxides）总量（单位：吨） NOx_Tons：排放的氮氧化物（Nitrogen Oxides）总量（单位：吨） CO_Tons：排放的一氧化碳（Carbon Monoxide）总量（单位：吨） PM10_Tons：排放的PM10总量（单位：吨）。PM10指空气动力学直径≤10微米的颗粒物 PM25_Tons：排放的PM2.5总量（单位：吨）。PM2.5指空气动力学直径≤2.5微米的颗粒物，属于PM10的子集 HAP_Tons：所有危险空气污染物（Hazardous Air Pollutants, HAPs）的总排放量（单位：吨）。危险空气污染物指美国环境保护署（U.S. Environmental Protection Agency, EPA）危险空气污染物名录中除与有毒空气污染物重叠外的化合物，名录可通过以下网址查询：https://www.epa.gov/haps/initial-list-hazardous-air-pollutants-modifications Tox_Tons：所有空气有毒物质的总排放量（单位：吨）。空气有毒物质指俄克拉荷马州行政法典（Oklahoma Administrative Code, OAC）252:100附录O中收录的化合物，不含与HAPs重叠的部分，详情可查阅：https://www.deq.ok.gov/wp-content/uploads/deqmainresources/100.pdf HAP_Tox_Tons：同时属于危险空气污染物和空气有毒物质的污染物总排放量（单位：吨） VOC_Total_Tons：总挥发性有机化合物（Volatile Organic Compounds, VOCs）排放量（单位：吨） Other_Tons：未归入上述类别的合规大气污染物排放量（单位：吨），当前涵盖臭氧和硫化氢。合规大气污染物详见俄克拉荷马州行政法典OAC 252:100附录P，详情可查阅：https://www.deq.ok.gov/wp-content/uploads/deqmainresources/100.pdf Facility_Classification：设施分类。其中： - 大型源（Major）：指大型排放源； - 合成小型源（Syn-Min, Synthetic Minor）：指合成小型排放源； - 小型源（Min, Minor）：指小型排放源。 当设施满足以下任一条件时，将被归类为大型源： 1. 某种合规大气污染物的潜在排放量≥100吨； 2. 单一危险空气污染物的潜在排放量≥10吨； 3. 所有危险空气污染物的总潜在排放量≥25吨。 潜在排放量未达大型源标准的设施，将根据其持有的许可类型被归类为合成小型源或小型源。此外，空气幕焚烧炉、大型城市生活垃圾填埋场，以及部分受危险空气污染物国家排放标准（National Emissions Standards for Hazardous Air Pollutants, NESHAPs）监管的排放源，即使排放量未达大型源标准，仍需申领大型源许可（分别详见40 CFR 60 第XXX子部分、40 CFR 60 第CCCC子部分以及OAC 252:100-8-3），因此此类设施将被归类为大型源。若持有小型源或合成小型源许可的设施，在报告年度内排放量超过大型源阈值，则将被归类为大型源。 Year_Emissions_Reported：排放报告的年度。绝大多数设施的报告年度应为2023年。对于按PBR登记且未主动上报的设施，该字段将沿用其最近一次上报的排放数据，直至其提交新的排放清单。按PBR登记的设施需在首次按PBR登记的当年提交排放清单，后续需遵循美国环境保护署国家排放清单的报送时间表。PBR登记设施的报送时间表详见俄克拉荷马州行政法典OAC 252:100-5-2.1，可通过以下网址查阅：https://www.deq.ok.gov/wp-content/uploads/deqmainresources/100.pdf
