Dear Ms. Boyle:

It has been determined that Clean Harbors of Baltimore, Inc. (Clean Harbors), is an optimal wastewater treatment site to treat and discharge the wastewater collected from rainwater, collected water, and stream water above and below the cleanup site of the Norfolk Southern Railroad derailment in East Palestine, OH that occurred February 3, 2023.

Details of the incident including testing and sampling results can be found at the EPA’s Website: https://www.epa.gov/oh/east-palestine-ohio-train-derailment-emergency-response

Clean Harbors proposes to begin receiving this wastewater immediately once approval is granted. The initial known quantity currently loaded in railcars is 675,000 gallons. The proposed treatment scheme will be carbon adsorption using 4x12 mesh reagglomerated carbon followed by inorganic metals removal as needed.

The primary constituent of concern is vinyl chloride. Data provided from Norfolk Southern indicate vinyl chloride between None Detect (ND) of 1 ppb to 62 ppb.

Data provided by Arcadis indicates PFOA and PFOS at 9.4 ppt and 8.7 ppt respectively in a 5 sample composite, just over EPA’s proposed drinking water standard of 4 ppt, with most other samples being ND. Clean Harbors will treat the wastewater by filtering through the reagglomerated carbon to produce an effluent below 4 ppt PFOA and PFOS. We look forward to your response and to helping our country with the proper management of this wastewater.

Very truly yours,

Bill Fornoff Director Laboratory

> the police union is the only union that is grifting in Baltimore city?

In Baltimore, only the Mosbys grift with the kind of entitlement FOP3 demonstrates.

>At a meeting Monday, the Baltimore County Council will vote on whether to help fund the study, which could represent a meaningful step forward for the idea, long discussed by cycling advocates — though it still has a long way to go. After the study, a final design would need to be completed and funding obtained for its construction.

>The study would assess possible routes to bridge the gap between the start of the NCR, also known as the Torrey C. Brown Rail Trail, off Ashland Road in Hunt Valley, to the northern end of the Jones Falls Trail, in Mount Washington Village. By car, the two trails are separated by about 12 miles.

>And while the NCR Trail ends at the Mason-Dixon Line, the Heritage Rail Trail picks up from there, allowing travelers to go up to York, Pennsylvania.
