Number of Environmental Studies Each Year

  • How many Environmental Impact Statements (EIS') and Environmental Assessments (EAs) are completed each year under the National Environmental Policy Act (NEPA) and what is the breakdown (number) by agency (EPA, Corps of Engineers, etc.) for these documents.


  • As soon as I posted my answer, I realized I got your name wrong. At least I was in the right ecosystem!!!! paf


  • Great response and very inciteful into the specific needs I had. Thanks!


  • Hello again watershed2-ga, Thanks for an interesting question. There were a total of 498 EIS's filed with EPA in 1997. The Department of Agriculture tops the list with 128 EIS'.

Projects........................................ 1 TOTAL ALL AGENCIES..........................................498 ---------------------------------- Unfortunately, CEQ stopped producing their annual reports after 1997. Although their website does provide some updates on environmental statistics, the NEPA data does not appear to be included. However, an EPA document, "Number of EISs Published by All Federal Agencies (1973 - 2001)", available at this site: http://www.epa.gov/compliance/resources/publications/nepa/index.html provides a more up-to-date graph of the total number of EIS' received by the Agency for each year, through 2001. As the graph makes clear, the total of 498 EIS for 1997 has not changed significantly in subsequent years, and has in fact, remained at the level of about 500 per year since the early 1990's. I hope this information meets your needs. If you need any additional explanation or information, just let me know through a request for clarification, and I'll be happy to assist you further.


  • I actually have an estimate for the number of EAs and EISa each year but would like verification, but the real important part is the number that generally fall out under each of the major agencies...at least those that are led by EPA, Corps, F&WS, BLM, National Forest Service, etc. I appreciate your help...but with more detail it would have more value...so thanks but I'll see if someone else can get at this one for me. I understand it is a challenge...I have been digging around myself for a while this morning. thanks again


  • Hello wetland2-ga, Nice to see you back! As you've found out yourself -- and as politicalguru has confirmed -- the data you are seeking are somewhat elusive. Here's what I've uncovered thus far: --I have very detailed breakouts for number of EIS' for each agency, and for major programs within agencies. For instance, data on the number of EIS' from the US Department of Energy are broken up into a number of categories: U.S. Department of Energy Power Facilities: Hydroelectric Power Facilities: Transmission Power Facilities: Nuclear (e.g., AEC, TVA) Power Facilities: Conservation and Other Comprehensive Resource Management Radioactive Waste Disposal Nuclear Development (e.g., Fuel, Reactors) Other Water Projects Fisheries Natural Gas and Oil: Transportation/Pipeline/Storage There are two important caveats though: (1) these are the number of EIS' *filed* (not necessarily finalized), and (2) the most recent data available is for 1997. 1997 data isn't as bad as it seems. According to more up-to-date totals for all EIS' filed each year, the annual grand total hasn't changed much since 1997, and the data for 2001 (most recent year available) is pretty much the same as 1997 -- for the *grand totals*. It's probably a reasonable assumption that the sub-totals for each agency haven't changed that much either...there are a few agencies that account for the lion's share, and then a trickle of EIS' from other agencies. As for EAs and FONSIs, I'm not sure data on the numbers done each year has ever been compiled...at least, I haven't found any. Let me know if the detailed 1997 agency-specific data for EIS' -- along with grand totals data through 2001 -- would suit you as an answer to your question.


  • Dear Wetland, I've found the numbers of studies conducted each year, but without the breakdown by agency. I hope that another researcher would manage to answer your question fully. If not, would you consider accepting my answer?


  • Thanks for your kind remarks and all those stars...they're always appreciated. Hope we'll see you back at GA soon. paf


  • Yes paalafa-ga...that seems very acceptable. Thanks!
