EPCRA §312PA

Pennsylvania Tier II reporting: how and where to file

File online in PATTS, the Pennsylvania Tier II System; a filing through any other program does not meet Pennsylvania's requirements. The report and the fee are due by March 1. $10 per chemical reported at or over the threshold, paid by check or money order to the Pennsylvania Hazardous Materials Response Fund. Family farms, service stations, government-owned buildings and public water and wastewater plants are fee-exempt but still file.

What Pennsylvania asks for

Each point below is followed by the state's own words, so you can check it against the source.

How to file

File online in PATTS, the Pennsylvania Tier II System; a filing through any other program does not meet Pennsylvania's requirements.

“Pennsylvania Tier II reports are filed online using the Pennsylvania Tier II System (PATTS).” source
“A Tier II submission via any other online or electronic reporting program does not meet the reporting obligations in Pennsylvania.” source

Deadline

The report and the fee are due by March 1.

“You must file the form and pay the fee by March 1st annually.” source

Fees

$10 per chemical reported at or over the threshold, paid by check or money order to the Pennsylvania Hazardous Materials Response Fund. Family farms, service stations, government-owned buildings and public water and wastewater plants are fee-exempt but still file.

“The department assesses a $10 per chemical fee for each substance that is reported at or over the reporting threshold.” source
“The state-level fee payment must be in the form of a check or money order and made payable to the Pennsylvania Hazardous Materials Response Fund.” source
“is your facility a family farm, service station, state, federal, or local government-owned building, or a publicly owned and operated water, wastewater treatment or sewer treatment plant” source

Fees

The LEPC bills its own Tier II fee separately; PATTS does not calculate it.

“PATTS does not calculate the LEPC Tier II fee invoice.” source
“The LEPC will forward a separate invoice due and payable to them.” source

State-specific rule

In Berks County, you also file in the county's own online Tier II system.

“For Berks County: The facility must file the Tier II report in PATTS to meet its state-level reporting requirements and also complete an online Tier II report in the Berks County reporting system.” source

The federal rule underneath

EPCRA section 312 applies to a facility that the OSHA HazCom Standard requires to keep an SDS for a hazardous chemical present at any one time at or above 10,000 lb, or at or above 500 lb or its threshold planning quantity, whichever is lower, for an extremely hazardous substance (40 CFR 370.10(a)). The report covers the previous calendar year and is due March 1 (40 CFR 370.45). Where Pennsylvania's rules above are stricter, they apply on top.

The full federal picture, Tier I versus Tier II, counting and penalties, is on the EPCRA Tier II hub. The list that feeds it is the chemical inventory.

HazComFast keeps each jobsite's chemical quantities next to its safety data sheets and exports the Tier II data as an Excel workbook, a CSV file and a PDF summary.
