The petrochemical renaissance in Pennsylvania has not delivered on its promises— the scale of public attention, subsidies, and economic development efforts directed toward petrochemicals is not commensurate with the sector’s actual contribution to the state’s economy.
Pennsylvania’s subsidies of the Shell Polymers Monaca plant have not spurred private investment in substantial industry expansion—nearly all other plants in the state pre-date the Shell plant and are not part of a wave of integrated development.
Despite promises from state authorities and fossil fuel companies, the refining and petrochemical-related industrial sector in Pennsylvania has shed jobs, not generated them.
Pollution problems at the Shell plant—including 62 notices of violations since 2017—highlight the need to assess risks and the compliance records of sponsors who seek public incentives for petrochemical projects.
Pennsylvania invested substantial government funding and tax credits in a Dutch-based international corporation’s petrochemical project—the Shell Polymers Monaca plant—in an attempt to help launch a “petrochemical renaissance” in the state.
It didn’t work.
The failure of Pennsylvania’s economic development initiatives to spur more private investment in major petrochemical developments—despite the ready access to natural gas liquids as feedstock—is a red flag.
The Institute for Energy Economics and Financial Analysis (IEEFA) examined the limited role of the petrochemical industry in Pennsylvania’s economic growth and jobs generation profile. The results make it hard to justify any more public incentives for the industry. IEEFA’s report finds:

The entire refining and petrochemical-related sector’s share of total employment in Pennsylvania has eroded over the same period, from roughly 0.2% to 0.09% today.
The state should reform its approach to economic development incentives. In particular, it should adopt a much more rigorous review of development plans before committing public funds or tax incentives to private projects. That review should include robust independent market analysis, objective analysis of potential community impacts, vigorous public outreach, and meaningful opportunities for public comments.
