The plan had been producing a deficit since 1982. Norsk Hydro made an agreement with the authorities where they would create 350 new permanent jobs, create a business fund and donate NOK 60 million for the construction of a new road, Route 37 along Lake Tinn. In 1988 Norsk Hydro terminated the ammonia production, and in 1991 they also closed down the production ammonium nitrate and potassium nitrate, along with the Rjukan Line. Within a few years the number of Norsk Hydro employees in Rjukan had been reduced from 1,760 to 530 people; 24 of these were employed by Norsk Transport operating the railway and railway ferries. All the employees were either retired or moved to other areas of Norsk Hydro's enterprise.
