In September 1998, EuRoPol GAZ received a Safety Certificate for the first section of the pipeline between Górzyca and Lwówek, which together with the Compliance Certificate awarded in June 1997 confirms that all construction works on that line have been carried out in compliance with the design documentation and the designer's recommendations. The certificate also confirms that the gas pipeline has been designed and executed in conformance to Polish and international standards and regulations and has been found safe and ready for commissioning. Both certificates were issued by Bureau Veritas.

In November 2000, Bureau Veritas issued two Safety Certificates for two sections of the pipeline: Odra River -Vistula River and Vistula River - Kondratki, which effectively cover the entire Polish section of the transit pipeline.

In 2000, EuRoPol GAZ received Compliance Certificates for the compressor and metering station at Kondratki and the compressor and control/metering station at Włocławek. In March 2001, the two facilities were awarded Safety Certificates. . All mentioned certificates were issued by Polski Rejestr Statków (The Polish Register of Ships).
