series of strategies and tactics to pursue emission reductions from mobile sources operating at and around Port Houston owned terminals over a 5 -year period from 2021 to 2025. This 2021 draft report uses data from a related report, the 2013 Goods Movement Emissions Inventory (GMEI) which is currently being updated. When GMEI data is updated later in 2021, it will be incorporated into this CASP. Because the baseline data in this draft is from 2013, all tactics and targets are subject to changes when CASP and GMEI are fully integrated later in the year. Progress in reducing mobile source emissions since the 2013 CASP includes the purchase of electric and hybrid vehicles and equipment; fleet upgrades; implementation of idling reduction policies; truck gate transaction processing improvements; additional introductions and upgrades of terminal operating technology; state and federal grant support for stakeholders; and active participation in working groups focused on emission reductions. At the same time, volumes have grown. Thus, updates will reflect these important factors. Nevertheless, the fundamental logic and emissions reduction efficacy of the recommended strategies is expected to remain in place. In addition, all focus on Clean Air should consider continuing innovation and new initiatives, some of which by definition are nascent and therefore will also lead to updates to these strategies as appropriate. Port Houston is currently engaged in a series of such discussions. The 2021 Clean Air Strategy Plan (CASP) proposes three core strategies, and 12 key tactics, summarized on the next page. These strategies and tactics include actions that may be under Port Houston’s control as well as initiatives that will require encouraging a collaborative approach with multiple stakeholders including asset owners, cargo shippers, technology providers, customers, policy makers and community. Detailed explanatory narratives are contained in the body of this report. 2021 Clean Air Strategy Plan Update Page | 1 2021 CASP Core Strategies and Key Tactics Strategy #1 — Replace Equipment Where Economically Feasible • Encourage Application of US EPA Heavy-Duty Truck Emission Standards • Upgrade Cargo Handling Equipment (CHE) that have reached their useful life • Encourage Locomotive Engine and Controls Replacement with Newer Technology • Encourage Harbor
