Pavement Coatings Technology Council v. United States Geological Survey, No. 20-5035 (D.C. Cir. 2021)
Annotate this Case
PCTC filed a request under the Freedom of Information Act (FOIA) seeking release of USGS records relating to the agency's coal tar sealant studies. USGS produced 52,000 pages of records, but withheld the modeling data and personally identifiable information relevant to this appeal. USGS withheld the model runs under Exemption Five on the ground that the release of the exploratory analysis would inhibit the ability to freely explore and analyze data without concern for external criticism. USGS withheld the house dust study participants' personal information under Exemption Six because release would constitute a clearly unwarranted invasion of personal privacy and would not serve a public interest because the pertinent scientific data associated in this category of records is already released. The parties filed cross-motions for summary judgment and the district court granted USGS's motion.
The DC Circuit reversed and remanded to the district court PCTC's claims regarding the urban lakes model runs withheld under Exemption Five, concluding that USGS failed to carry its burden to show that the model runs are pre-decisional. Furthermore, USGS failed to prove beyond dispute that the model runs are deliberative. Therefore, the absence of evidence establishing that the requested model runs are protected from disclosure amounts to the agency's failure to establish that it is entitled to judgment as a matter of law. However, the court affirmed the district court's decision to withhold the house dust study location information under Exemption Six. The court explained that the study participants have a greater than de minimis privacy interest in their addresses, household compositions, smoking and cooking habits, and the extensive personal details included in the questionnaires. The court further explained that releasing their addresses serves no cognizable public interest.
