Mississippi Code Title 49. Conservation and Ecology § 49-27-9

(1) No regulated activity shall affect any coastal wetlands without a permit unless excluded in Section 49-27-7. Any person proposing to conduct or cause to be conducted a regulated activity shall file an application for a permit with the commission in such form and with such information as the commission may prescribe. An application fee in an amount of Fifty Dollars ($50.00) for residential type regulated activity and Five Hundred Dollars ($500.00) for commercial and industrial type related activity shall accompany each application and shall be payable to the commission. No permit shall be required for a regulated activity as defined in Section 49-27-5(c)(v) if such activity is an activity by a water dependent industry, nor shall a permit be required pursuant to Section 49-27-5(c)(v) of any individual who seeks to construct a home, fishing camp or similar structure on his own property.

(2) If the commission determines that the activity, area or entity is exempt or requires no permit, and that the activity, area or entity complies with the notification requirement and the coastal wetland policy as required under Section 49-27-7, the commission may reduce the application fee by fifty percent (50%).
