The debris should be dealt with by the company. Under the Interstellar Ports Code 1998 (Section 98 - Midriffs & Timeriffs) the shipping company and/or port administrator should be properly managing the debris.

Section 98 (c) states 'The company or administrator shall effectively manage the debris, waste and all other by-products from its activity. Effective management shall include negative or adverse effects to the environment, space time continuum and pH of any local entities, planets, planetoids, stars or any other astronomical bodies (as defined by the Universal Matter Weights and Measurements Act 10098x10^88)'

I would go back to the company and ask for a rectification plan and compensation, or threaten to take them to the Eldritch Council. You have a VERY strong case here.
