The Bilac-Santa Maria Gas Pipeline, also known as the Chimarrão B Pipeline, is a proposed natural gas pipeline that would run through the southern Brazilian states of Paraná, Santa Catarina and Rio Grande do Sul.


Starting at a junction with the Gasbol gas pipeline in Bilac (São Paulo state), the pipeline would run 1237 km south to a junction with the proposed Uruguaiana-Porto Alegre pipeline near Santa Maria in Rio Grande do Sul state. The pipeline's proposed route passes through Indiana (São Paulo state), Porecatu, Apucarana, and Guarapuava (Paraná state), Videira and Joaçaba (Santa Catarina state), and Erechim, Passo Fundo and Cruz Alta (Rio Grande do Sul state).[1]

The Bilac-Santa Maria Gas Pipeline is one of several new pipelines proposed in a November 2020 government plan to expand Brazil's natural gas transmission network. The 1237-kilometer, 20-inch pipeline would have an estimated development cost of R$ 12.4 billion (12.4 billion Brazilian reais) and the capacity to deliver 8 million cubic meters of natural gas per day to customers in the southern states of Paraná, Santa Catarina and Rio Grande do Sul.[1]

In 2021 and 2022, various news stories and government reports continued to refer to the Chimarrão pipeline as an active project. However, as of July 2022 plans remained in the speculative stage.[2][3]
