Renewal of an emission permit for a detergents plant

In this project, we submitted a request to renew an emission permit for a plant belonging to the chemical sector. The factory produces hundreds of basic products and finished products for companies in Israel and around the world. In addition to its complex operations, the plant was planned to undergo process and structural changes in a time window of less than 7 years, so we were required to include future processes in the current application for the renewal of the emission permit.

The factory is decades old, and some of the processes that exist in it are no longer economical and do not always meet the new standards for preserving the environment, so they will be canceled in the coming years. As part of the environmental program for efficiency, wastewater is separated, some of which is reused in the production processes, and a wastewater treatment facility was established there to treat the remaining wastewater before being discharged into the sewer, new and standard chimneys were upgraded, and schedules were established for auditing and sampling the production systems and storage tanks. In addition, a transition to the use of gas as a replacement for burning fuel oil in the steam boilers and the implementation of an energy management system according to the ISO 50001 standard.

During the project, many complex processes that take place at the same time were examined, we reviewed and summarized the names of all the raw materials and their annual consumption, we integrated processes and samples, we mapped emissions from a variety of sources - focal and non-focal, we described the production processes and calculated mass balances that weigh the percentage of material consumed compared to its emission into the air and sewage.

Pursuant to the Clean Air Law, 2008, an emission permit makes information about the plant's impact on the environment accessible to the public. However, the plant retains the right to confidentiality of information about production processes and operational data, which are defined as "commercial secrets", according to criteria established by law.

For this reason, along with the copy of the application for the renewal of the emission permit, two additional copies must be submitted; One is defined as a request to hide information and it is examined by the emission permit supervisor in the Air Quality and Climate Change Division of the Ministry of Environmental Protection. After its approval, another copy is submitted in which the details approved as confidential are blacked out, and this is also the copy that is published for public review.

The complexity of the process of submitting an application for an emission permit requires a physical acquaintance with the plant, therefore at the beginning of the project we held a meeting and a tour to familiarize ourselves with the contacts and with the production processes, storage and the map of the plant. Further meetings and intensive communication were held with the factory in order to meet the required schedules for submitting an emission permit.
